If you have a tooth that just doesn't look good because of decay or injury, a porcelain laminate veneer is probably a good way to make it look as good as it ever did — and maybe even better! Dental veneers are composed of thin layers of dental ceramic material. They essentially replace the original tooth enamel and require preparation of the tooth by removing a small amount of enamel to allow room for the placement of the veneer.
Recently, more and more dentists have been using minimal prep or prepless techniques that do not require this preparation. In such cases, the porcelain is bonded directly to the outer layer of the tooth's enamel. Highly skilled dental technicians can design a custom-fit veneer that feathers into the tooth just short of the gum line.
Prepless techniques cannot be used in all situations, but when they are used appropriately the results are beautiful and very stable. Should you get prepless veneers? The following is a list of advantages and disadvantages of prepless veneers.
Advantages of prepless veneers include:
- Tooth preparation or reduction is not needed, leaving the original tooth whole.
- They are not placed under the gum tissue, eliminating the possibility that the restorations negatively impact the gum tissue.
- They can be used to change the appearance of teeth that are too small or misshapen making the teeth look larger and eliminate unwanted spacing.
- They can be used to “lengthen” teeth that have been worn down by grinding.
- Since the underlying tooth has not been reduced, prepless veneers are reversible and practically risk-free.
- There are many cosmetic situations in which they cannot be used, and traditional veneers (requiring preparation) must be used instead.
- Prepless veneers cannot be used in cases in which orthodontic treatment is recommended to move the teeth, such as improper tooth position, poor bite, or a poor facial profile.
- Since they are added on to existing tooth structure, they do not work for teeth that are relatively large or in a forward position in a smile.
- They do not usually work for lower teeth because of space restrictions.
- They cannot replace lost or damaged enamel.
Working with prepless veneers requires special skills and training. Please discuss our credentials and experience with us when you inquire about this technique. We can assess your specific situation and let you know whether restoration without the drill is appropriate for you.

If your teeth have a worn appearance, it's possible you have a habit you're not even aware of: clenching or grinding your teeth. Also called “bruxism,” this destructive action causes your top and bottom teeth to come together or scrape past each other with a force that's many times what is normal for biting and chewing.
So what's normal? This can be expressed in terms of pounds. An adult usually exerts a force of 13-23 pounds to bite or chew food. But we have the potential to generate as much as 230 pounds of force, or 10 times what's normal. A “parafunctional” force of this magnitude applied repeatedly is bound to stress your teeth and other areas of your oral system. Besides wearing away the enamel of your teeth — and maybe even some of the softer dentin layer underneath — you may experience muscle spasms or pain in your jaw joints. Serious cases of wear can lead to “bite collapse” in which your face actually changes shape as your cheeks and lips lose support. This can make you look prematurely aged.
What can be done? To prevent further wear, we can fabricate for you a thin, plastic mouthguard that will protect your teeth at night or during times of intense stress. We can also recommend ways to temporarily relieve the discomfort that your grinding/clenching habits can cause. Heat and/or anti-inflammatory medication, for example, can be helpful.
If your tooth wear is minor (raggedness along the biting edge of a tooth or teeth) you may not need any restorative work. However, if tooth wear has already caused changes to your teeth and bite that you find aesthetically or functionally unacceptable, we can restore lost tooth structure in a variety of ways. Veneers and crowns are two examples.

Getting enough sleep is necessary for good health. We all know how energetic we feel when we are sleeping well at night. Yet, many of us do not feel rested, even after seven or eight hours of sleep. Let's answer some common questions about snoring and sleep apnea, problems that are often called sleep related breathing disorders (SRBD).
What is the purpose of sleep?
Scientists know we need sleep, at a particularly deep level, to be rested, but they are not sure why we need sleep. Sleep may have evolved as a way to conserve energy in the body, to conserve food supplies, or to reduce our risk during darkness. Sleep appears to give the brain a chance to store and organize its information and the body a chance to recuperate. Sleep studies have shown that in order to get the full benefits of sleep we need to sleep long and deeply enough to enter into a series of sleep cycles including Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM) sleep.
What kinds of problems get in the way of the type of sleep we need?
There are eight main categories of sleep disorders, but the ones affecting the largest numbers of people are insomnia, SRBD, and Circadian Rhythm Sleep Disorders. SRBDs include snoring and Obstructive Sleep Apnea (OSA), which is a serious health problem.
How do I know if I have OSA or another SRBD?
Often, your bed-partner will tell you that you snore. Chronic loud snoring is an indicator of OSA. To make a diagnosis your physician must take a thorough sleep and medical history. The diagnosis may then be confirmed by a study in a sleep lab.
What causes sleep apnea or OSA?
Snoring and OSA happen when your tongue and other soft tissues in the back of your throat collapse backwards and block airflow through your upper airway or windpipe. You may briefly awaken as many as 50 times per night because of these breathing lapses. These brief awakenings, called micro-arousals, keep you from reaching the deep stage of sleep your body needs.
What are the treatments for sleep apnea?
Treatments include CPAP therapy, in which patients wear a mask while sleeping. The mask pushes air through the airway, keeping it open. In Oral Appliance Therapy (OAT) patients wear a device that moves the lower jaw forward, allowing more room for air to move down the airway. Oral surgical procedures and orthodontic approaches also have the goal of moving the tongue away from the throat. These are all treatments that can be carried out by a dentist who has training and experience in treatment of sleep disorders.

For years, lasers have revolutionized the medical industry and now they are beginning to do the same within the field of dentistry. However, anytime new technologies are introduced, people naturally will have questions. Here is a list of frequently asked questions (FAQs).
What is a laser?
Lasers are beams of light that are a single wavelength and color. Laser is an acronym derived from “Light Amplification by Stimulated Emission of Radiation.”
How are they different from regular sunlight?
White light is made up of light with many wavelengths corresponding to the visible spectrum comprising the rainbow (red, orange, yellow, green, blue, indigo, and violet). Laser light consists of beams of a single color and hence a single wavelength of light, concentrated to a high energy level, which can penetrate living tissue.
How are they used in dentistry?
Dental laser usage typically falls into three categories: disease diagnosis; soft tissue procedures of the gums, lips and tongue; and hard tissue procedures of the bone or tooth enamel and dentin. Examples of the most common hard tissue treatments include the diagnosis and removal of tooth decay, while the most common soft tissue treatments include the removal of gum tissue as it relates to cosmetic dentistry and the treatment of gum disease.
Are they safe?
Absolutely! Before blazing a trail in the field of dentistry, lasers have been used for years in the medical field with research evidence and the FDA approving both their safety and efficacy. In fact, they are minimally invasive and can result in less tissue removal, less bleeding and less discomfort for patients after surgery. And what could be better than that?

If you fear a visit to the dentist, you are not alone. Studies have shown that up to 75% of people surveyed have some fear of dental visits, and 10 to 15% fear the dentist so much that they avoid any dental treatment. This can have serious repercussions, leading to toothaches, infections, and loss of teeth. Poor oral health can even negatively affect your general state of health.
Here's the good news. Even people who are the most afraid of the dentist can learn to reduce their fear and feel calm and safe during a dental visit.
Dental fears develop when people have bad dental experiences. For many, the problem is a sense of loss of control. Sometimes, fears are based on stories people have heard or even movies they have seen.
The feeling of being afraid reinforces your fear. If you experience the rapid heartbeat, sweaty palms, tensed muscles, and other symptoms of fear while in the dentist chair, you are likely to remember these unpleasant feelings afterward and become even more fearful. In order to reverse this process, you need to begin to associate dental visits with good experiences and a sense of control. Here's how we can help you do this:
- Know that you are not alone and we are here to help you.
- Talk to us about your fears. We are sure to listen and not be judgmental. If you don't talk about it, you can't get over it.
- We will start by doing things that cause only mild or no anxiety. We want each visit to be a good experience, so you are able to leave our office with a feeling that it was okay, and you can do it again.
- Our goal is for you to overcome your fear. We will make this a priority and that priority is as important as “fixing your teeth.” We will be happy to talk about the time and fees associated with your treatment so that you can overcome your fear and gain a sense of control of the situation.
- It took a while for your fears to develop, so you should realize that it will also take a while to get over them. We will spend as much time as you need to get over your fears and will not rush you into doing anything for which you are not ready.
