For many people, when they hear the term “laser,” they immediately envision a futuristic science fiction movie. However, did you know that lasers have been used in the medical industry for years? Furthermore, this revolutionary technology is now beginning to do the same within the field of dentistry.

Lasers get their name from “Light Amplification by Stimulated Emission of Radiation” and are literally beams of light that have a single wavelength. Unlike traditional white light or daylight that is a continuum of light with many wavelengths corresponding to the visible spectrum or rainbow, a laser light beam is just a single color.

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. For example, common uses include diagnosing cavities, treating disease, and removing both diseased gum tissues and tooth structure, as in decay. They were first used in dentistry for soft tissue surgery such as gum line reshaping procedures and tissue testing (biopsies). In 1997, dentists started using them for removing decay and preparing the tooth enamel and dentin in preparation for fillings. More recently, dentists are using lasers to help detect and diagnose dental disease, as they are especially helpful in identifying dysplastic (“dys” – altered; “plasia” – growth) or precancerous tissue as well as cancerous tissues. Thus they have been used for removing both malignant (cancerous) and benign (non-cancerous) lesions in some cases.

As you now see, laser dentistry is an important tool we use at our office to provide our patients with optimal dental care and treatments.

If you think your child is too young to need root canal treatment, think again — there is no age limit for this treatment. If his/her primary (baby) teeth have been injured, or if decay has advanced deep into the roots of your child's teeth, a root canal treatment to stabilize teeth may be needed. Root canal treatment removes infection from the pulp, the living tissue that is found inside the tooth's roots. The pulp contains the tooth's nerves, so tooth pain is often an indication that decay has moved into the pulp.

When performing root canal treatment on primary teeth, we must keep in mind that the primary teeth's roots will be resorbed as part of the normal process in which the body makes room for the growing permanent teeth that will take their place.

If a child experiences tooth pain that is related to changes of temperature or pressure, or exposure to sweet or acidic foods, the infection is likely to be minor and easily repaired. But if he or she feels a constant or throbbing pain regardless of stimulation, it may indicate an extensive infection of the pulp and surrounding area.

If the infection is advanced, the baby tooth may have to be removed. But if baby teeth are lost prematurely, a malocclusion (from “mal” meaning bad and “occlusion” meaning bite) can easily result; so we make every effort to keep the baby teeth in place to guide the permanent teeth that are forming underneath them, inside the child's jaw. In such cases an endodontist (from the root “endo” meaning inside and “dont” meaning tooth) or pediatric dentist may perform root canal treatment, removing the diseased and infected pulp from within the tooth's roots and replacing it with a substance that can be absorbed when it is time for the baby tooth's roots to be resorbed naturally.

When baby teeth are injured through a fall or blow to the face (referred to as traumatic injury) they may develop discoloration varying from yellow to dark gray. This is a sign of damage to the pulp tissues inside the tooth's roots. Dark gray discoloration often indicates that the pulp tissues have died. In such cases root canal treatment is needed to remove the dead tissue. If a tooth is completely knocked out of the child's mouth, most dentists agree that it should not be replanted because of the risk of damage to the developing tooth underneath.

Root canal treatment for baby teeth is a better choice than tooth removal if at all possible. It helps a child retain full function of their teeth, jaws and tongue, preventing speech problems, and it helps guide the permanent teeth into their proper places.

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.

Disadvantages include:

• 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.

You may have noticed, as you get older, that the enamel of your teeth is looking worn in certain areas. Sometimes tooth wear takes the form of a minor chipping or fracturing at the incisal (cutting) edges of the teeth, or a loss of tooth material from the area near the gum line. In more severe cases, worn teeth look quite a bit smaller than they used to. Why does this happen?

Some wear with age is natural. But too much wear can interfere with your bite, expose more sensitive inner parts of the tooth to decay, and give you a more aged appearance.

There are things you can control that affect wear:

Your habits: Clenching or grinding habits, also called “bruxism,” is a major cause of tooth wear. The motion of teeth sliding over each other with forces that are beyond what's normal for biting or chewing causes a mechanical removal of tooth enamel. This can happen during sleep or periods of high stress. In either case there are therapies available, such as a thin, professionally made mouthguard that prevents your teeth from coming into contact with each other. Holding foreign objects, such as nails and bobby pins, between your teeth can also cause wear.

Your diet: Tooth enamel can be eroded (dissolved away) by acidic beverages, such as sodas, sports drinks and juices. Frequent snacking on sugary foods encourages the growth of oral bacteria that produce acid as a byproduct — also leaving your teeth vulnerable to tooth decay. Your saliva can buffer the effects of the acid in your mouth in about half an hour; if you consume these types of foods and beverages continually, there won't be enough time for this to work.

We can restore the appearance and function of worn teeth in a variety of ways. Porcelain crowns and veneers, for example, can re-establish the normal thickness and length of teeth while improving their color and giving you a more youthful appearance.

A pregnant woman has a lot to think about while preparing to welcome a new member of her family. It's important to think about her oral health as well. She is sharing her body with the developing infant, so problems with her health — including her dental health — can affect the baby. The following facts will help you understand the relationship between oral health and pregnancy.

1. A baby's primary (baby) teeth begin to form during the sixth week of pregnancy. They begin to form their enamel (the hard outer layer of the teeth) and dentin layer (just under the enamel) at about the third or fourth month. The calcium, phosphorous, and protein that are needed for these structures must all be provided by the mother's diet.
2. A good diet for a pregnant mother, in order to provide for both her needs and those of the fetus (the developing baby), includes whole grains, fruits, vegetables — including green leafy vegetables — proteins and dairy products. A doctor may also recommend iron and/or folic acid supplements.
3. If the mother's diet does not provide enough calcium for the baby's bones and teeth, it will come from calcium stored in her bones — not from her teeth. The old idea that a mother's teeth lose calcium during pregnancy has been found to be a myth.
4. Progesterone, a normal female hormone, is elevated during pregnancy. This hormone stimulates production of prostaglandins, substances that cause inflammation in gum tissues if the bacteria that cause periodontal (gum) disease are present. The resulting swelling, redness, and sensitive gum tissues, called pregnancy gingivitis, are common during the second to eighth months of pregnancy.
5. The bacteria involved in periodontal disease can affect whole body conditions such as heart disease and strokes, diabetes, and respiratory diseases. The inflammation resulting from such bacteria can also cause premature delivery (birth before 37 weeks of pregnancy) or low birth weight in the baby.
6. Periodontal disease is also related to pre-eclampsia, or high blood pressure, during pregnancy.
7. Dental x-rays do not expose the mother to very high radiation, but in any case every precaution is taken to minimize exposure to the fetus. These include a leaded apron that shields the baby from exposure.
8. Most drugs commonly used in dentistry, including local anesthetics, can safely be given to pregnant women without affecting the fetus. However, it is important to let your dentist know you are pregnant before embarking on any treatment to make sure anything that is done will be safe for the fetus and its developing teeth.
