Dental Anesthetics

For many patients, the dreaded "shot" is the worst part of any dental procedure. Although you may find needles objectionable, local anesthesia makes modern dentistry comfortable, convenient and safe. Read on to learn how this quick and easy step is crucial to your dental care!

For starters, we use local anesthetics to block the sensation of pain in areas of the mouth that will be come irritated during dental treatment. Dental enamel, root canal treated teeth and implant crowns do not have direct connections to live nerve fibers, and thus do not benefit from anesthesia. This is why placing sealants on children does not require a shot- only the enamel and sealant material are affected during the procedure.

While you may picture Novocain when you think of dental anesthetics, this product hasn't been used in mainstream practice for years. Modern formulations such as Lidocaine and Articaine are easier to control and much safer for the patient (lower toxicity). These medications block pain and touch sensation for two to four before wearing off back to normal. However, they cannot block the nerves that conduct vibration and pressure sensation. These fibers have a different lining that requires much more medication to anesthetize. 

At our office, we deliver anesthesia with the Wand system. Here, a single-use syringe and vial are computer controlled to deliver the medication under constant pressure. This gives the dentist greater power over the location and amount of anesthesia used, while increasing patient comfort. If you would like to know more about local anesthesia and how we use it in modern dentistry, please give our office a call!

Helpful Infographic on Cracked Teeth

A cracked tooth can be anything from a minor inconvenience to a major annoyance. Many times, small cracks begin showing painful symptoms only after weeks or months of continuous pressure  and abuse. Our friends at the Spear Institute put together this helpful guide on what to do and what to expect when you have a cracked tooth. As with most things in dentistry, the key is early detection and intervention. The sooner we can work on repairing a dental problem, the more likely the tooth can be saved. Take a look!

Temporary tooth replacement for implants

This is an example of a typical stayplate with hidden metal/acrylic.

If you have been looking to have a tooth replaced with a dental implant, you were probably surprised to learn about the treatment time line. Some television shows and ads make implants seem like a single step process- you go to the dentist, they place the titanium anchor and attach a crown in a single visit. On the contrary, most implants need about six months to fully heal before being fitted with a crown. For patients replacing anterior teeth, this can be a huge esthetic concern. 

When preparing for anterior implants, careful planning and consideration can make the difference between "acceptable" results and "outstanding" results. With this in mind, we typically do not recommend putting an immediate load on the implant (placing a crown at the same visit as the surgery). This allows time for proper bone healing and gives us a chance to perfect the soft tissue around the anchor and create a natural gum line. However, you certainly can't walk around for six months with a missing front tooth!

To fill in the time between implant surgery and crown placement, we typically have our lab create a temporary partial denture called a stayplate. These devices, also known as flippers, are removable partial dentures that are made prior to implant placement. At the same visit as your surgery, you leave the office with the fitted stayplate replacing the missing tooth or teeth. They are typically made out of acrylic and metal and more closely resemble orthodontic retainers than traditional dentures. In most instances, the clasps, wires and acrylic are fully hidden from your smile, presenting only the replaced tooth!

We use stayplates as temporary tooth replacements in a number of circumstances. However, we do not use them on the back teeth (molars and premolars) to restore chewing function. Due to the design and materials used in stayplates, they cannot be used for eating and can cause irritation to the underlying gum tissue. For a full picture on stayplates and what they can accomplish, please give our office a call! 

Smile Repair Using Bonding and Emax Crown

Today's patient came to us with complaints of mismatched central incisors. The patient's right incisor had a large composite (tooth colored) filing that had become worn and stained over time. Their left incisor had a crown that was too light and opaque compared to the surrounding teeth. Both of these esthetic problems are very common, as teeth tend to age differently from the materials we use in dentistry. Composite fillings pick up stain and erode more quickly than enamel while crowns do not respond to color changes like surrounding teeth. The result is that restorations in the front of the mouth gradually become more obvious and less natural over time. 

Dr. Kari Ann Hong set out to repair this smile by placing a new filling on the left incisor and using an Emax Lithium Disilicate crown on the right. The new restorations add natural coloring, opacity and shape back to the patient's smile. In the before picture, the existing dental work is fairly obvious. The new crown and filling blend naturally and bring harmony back to this smile!

Options for Straighter Teeth

Orthodontics represent one of the most commonly performed dental procedures outside of cleaning and fillings. Every year, thousands of children, teens and adults begin treatment towards straighter teeth. Take a look at some of the considerations you will want to make in obtaining that perfect smile!

First and foremost, orthodontics should only be attempted under the supervision of a licensed dentist/orthodontist. No online guide or mail order kit will be able to bring the expertise of a professional in creating a perfect smile. Even something as simple as closing the gap between your two front teeth can cause irreparable damage. At the very least, you will be wasting time and money on "procedures" that get you nowhere. At the worst, you could end up losing a tooth (particularly true for the rubber band gap closers available online). 

Many younger patients will be best suited for traditional metal band and bracket braces. This treatment is predictable, easy to adjust and can straighten many different types of crooked teeth. Braces are usually worn for about 24 months and are overseen by an orthodontist. The hallmark of this treatment are the non-removable wire and brackets. Children (who typically have poor compliance) do not have the option of "not wearing" their appliance. Conversely, flossing and brushing around the wires can be difficult, making good oral hygiene a must while in braces. 

On the opposite end of the spectrum are clear aligners, like the always popular Invisalign appliance. This treatment is performed by general dentists and orthodontists alike to correct most types of spacing problems. Our office uses Invisalign to correct many mild to moderate orthodontic concerns. Because aligners are clear plastic and can be removed, they are often the choice for individuals with cosmetic requirements. Unfortunately, since the aligners are not physically attached to the teeth, some movements are simply not possible. Furthermore, this treatment relies on patient compliance- the retainers must be worn for 20+ hours a day!

In some specific circumstances, crowns and veneers can also fix gaps and crowding between the teeth. A common application would be placing crowns on the two front teeth to fix a gap by creating a more cosmetic contour. That said, orthodontics are usually the first choice if the only problem is spacing between teeth.

Dental Questions: Can eating fruit harm your teeth?

Fruits and vegetables are often hailed as the healthiest parts of a balanced diet. They bring vitamins, minerals and antioxidants to almost every dish, while avoiding harmful fats and oils. However, since many fruits are acidic and high in sugars, they can be potentially harmful to your teeth.

As with all foods, the quantity and quality of the fruit you eat doesn't matter as much as the duration in which it is consumed. The bacteria in your mouth don't care if it's organic and natural or processed and preserved. To them, sugar is sugar. As such, the best way you can modify the bacteria's response is to limit the time that your teeth are exposed to carbohydrates.

Every time we eat or drink our mouths turn to an acidic state for 30 minutes. During this period, dental enamel becomes softened and prone to decay. In this sense, someone who eats every 30 minutes spends nearly the entire day damaging their teeth. This is why snacking on apple slices all day is more harmful than eating a single candy bar immediately after a meal (in a strictly dental sense).  

Another factor you can control is the consistency of the foods you eat. Sticky and dry fruits like raisins can be much more harmful than something crisp and moist like pear or apple. This is particularly true in children, who don't have a natural tendency to pick food out of their teeth. 

In total, fruit makes an excellent healthy snack, but must be enjoyed in moderation. Realize that it still contains acids and sugars that fuel the tooth decay process. As with any sweet food, we recommend keeping snacking on fruits to a minimum and sticking to eating only at mealtime. If you must snack, make sure that you are cleaning your teeth of any residual food and rinsing with water when you're finished. If you have any more questions on diets, tooth decay and cavity prevention, please give our office a call!

Molar Replacement with Implant and Zirconia Crown

Although studies show that the population's general oral health is improving, over half of all adults will be missing at least one tooth by retirement age. In the past, single tooth replacement options were limited to bridges (that required drilling on the teeth adjacent to the missing area) or removable dentures. Many patients found these options unpleasing and sought after something that could replicate the function and convenience of natural teeth. Fortunately, implants can offer exactly that- a fixed tooth replacement that functions independently of the adjacent teeth!

For today's patient, a missing first molar was replaced using a titanium implant and zirconia crown. As with any procedure, careful planning and communication between our office and the surgeon's office ensured that the implant was placed exactly according to the patient's needs. One the bone was given time to heal and osseointegrate (grow new bone around the titanium screw), we took impressions and had our lab create a durable and esthetic replacement crown. A process like this one typically takes about 4-6 months from implant placement to final crown delivery, depending largely on the body's healing process. 

While implants are a fantastic treatment option, they are not appropriate for every patient in every circumstance. You must be healthy enough for the placement surgery and have enough strong healthy bone to support the implant. Additionally, there are certain treatment options/scenarios where implants simply will not work. If you would like to know more about implants and how we use them to replace teeth, please give  give our office a call!

Dental Sealants

February is the official National Children's Dental Health Month, as recognized by the ADA. Thousand Oaks Family Dentistry will be rolling out weekly topics relating to pediatric dentistry all month long. Make sure to check back regularly to catch all the great information. 

While Dental Sealants are appropriate for patients of all ages, they are most commonly placed on kids and teens to maximize their preventative ability. The pit and groove patterns of the chewing teeth create near-perfect food traps. In fact, they are often so deep and narrow that toothbrush bristles cannot reach the furthest depths. Bacteria can then grow in these areas undisturbed and fueled by a constant food source. This is the general pattern behind cavities on the biting (occlusal) surfaces of teeth.  

Sealants interrupt this process by physically filling in the deepest parts of these pits and grooves. With the space gone, the risk of developing cavities in these areas is significantly decreased. The process of placing a sealant takes about 45 minutes (depending on the number of teeth) and does not require a shot. We start by cleaning the teeth with gentle air abrasion. Once the teeth are free of saliva, bacteria and food, we place the material into all deep grooves. The procedure is finished by checking the patient's bite and making sure the sealant is well bonded to the tooth. 

It is important to understand that sealants only protect against decay on the biting surfaces of the teeth. Cavities between the teeth (another common area) are only prevented by proper brushing and flossing. Additionally, it is worth noting that sealants can fall off over time and are much more likely to fail if the patient's home care is insufficient. As always, the key is brushing twice a day with fluoride toothpaste and flossing daily. If you have any more questions about sealants, what they do or why we place them, please give our office a call!

The Primary Teeth

February is the official National Children's Dental Health Month, as recognized by the ADA. Thousand Oaks Family Dentistry will be rolling out weekly topics relating to pediatric dentistry all month long. Make sure to check back regularly to catch all the great information. 

One of the most miraculous features of the human body is our ability to develop two full sets of teeth. Baby teeth (also known as "deciduous" or "primary" teeth) begin developing before birth and are completely shed by about 12 years of age. During this time, they serve a number of developmental and nutritional purposes. 

For starters, baby teeth are usually whiter and more widely spaced than adult teeth. They also have relatively larger nerve spaces and thinner enamel, meaning the likelihood of a cavity going to the tooth nerve is much higher. There are also no baby premolars- just incisors, canines and molars. 

A handy guide illustrating when you should expect baby teeth to erupt and shed. It is important to note that the ranges are estimates and many children will fall outside these dates. 

In their most basic form, primary teeth allow a child to properly chew and break down food for digestion. They also act as guides to save space and allow the permanent teeth to grow in. This is one of the guiding principles of phase one orthodontics, or braces on primary teeth. It is also believed that the deciduous teeth play an important role in the development of facial bones. Finally, children's teeth are crucial in learning phonetics and vocalizing specific sounds. 

WIth all this in mind, you can see how losing baby teeth early can have a significant impact on childhood development. Premature toothlessness in children is often associated with pain, problems eating, lower self esteem and greater orthodontic complications later in life. The best way to prevent these problems is regular dental examinations coupled with good oral hygiene at home. Positive parental attitudes towards dentistry can go a long way in keeping children's teeth healthy and well protected.

National Children's Dental Health Month!

February is the official National Children's Dental Health Month, as recognized by the ADA. Thousand Oaks Family Dentistry will be rolling out weekly topics relating to pediatric dentistry all month long. Make sure to check back regularly to catch all the great information. 

For our first topic, we would like to discuss your child's first dental appointment. This visit should take place place at one year of age or when the first tooth erupts (Usually the mandibular incisors at 6-12 months). The first appointment serves as an important introduction for future dental care. Our office reserves this time to examine the mouth for any developmental problems and have a discussion on oral health with the parents. There are typically no x-rays or cleanings at this visit- just a checkup!

Just as important as the actual examination, this type of appointment sets the stage for a lifetime of positive dental experiences. Many less fortunate children will first see a dentist when they have a toothache and will forever associate the pain, confusion and anxiety with dental offices. We hope to start your children off with a fun and easy appointment that gets them excited to return for cleanings and exams! If you would like to know more about the dental services we provide for children or to book an appointment for your young ones, please give our office a call!
