Your self-image has a lot to do with how you feel about your appearance — and particularly your smile. If you are unhappy with the way you look, cosmetic dentistry may be the answer to your problems.
- What do we mean by cosmetic dentistry? The word “cosmetic” refers to beneficial changes in appearance. Thus cosmetic dentistry is all dental work that restores or improves a person's appearance.
- What is a cosmetic dentist? Every dentist learns to do procedures in a way that conserves or improves a patient's appearance. Some dentists continue to study and specialize in procedures that are done specifically for the purpose of enhancing a person's appearance.
- What is a smile analysis? The first step to improving your smile, this analysis involves a study of all the elements of your smile — teeth appearance and alignment, gums, jaws — and also your facial features and how they all fit together.
- How can I choose the right cosmetic dentist? Ask your dentist about his or her training and experience. Ask for photos of previous work. You may need to select more than one person, working as a team to take best advantage of each one's experience, skills, and training.
- What can be done to improve a smile using 21st century techniques? We are fortunate to live in times in which numerous options are available. These include making teeth whiter; altering their size, shape, balance, color, and alignment; filling in parts of teeth that are missing because of decay or injury; and even replacing teeth that are missing entirely.
- How can chipped or discolored front teeth be restored? This can often be done by bonding with composite resin.
- How can damaged back teeth be restored? Back teeth with cavities or traumatic injuries can now be repaired with non-metallic tooth-colored material that bonds to the tooth substance.
- What techniques can be used to correct more severe problems? Porcelain veneers, thin layers of porcelain material, can be used to change the appearance of misshapen or undersized teeth. Porcelain crowns can be used to replace the part of the tooth that rises above the gums.
- How can we change the position of teeth that do not meet together well? Orthodontists are dentists who specialize in correcting malocclusions (bad bites). They use traditional braces or clear aligners to move teeth into more attractive and functional positions.
- What if some teeth are missing? A dental implant replaces the root of a missing tooth. A porcelain crown that looks just like a natural tooth can then be connected to the implant.

When choosing among different ways to solve a problem, knowledge is power. In the case of selecting the best repair for a dental problem, count on your team of dental professionals to advise you. But you as the patient make the final decision, and it helps to thoroughly understand the different options, their advantages and disadvantages. If you have a chipped or broken front tooth, your likely repair options are composite resin or porcelain veneer.
Composite resins are synthetic materials that can be colored to match your natural teeth. The material is bonded to the tooth surface using adhesives that become part of the tooth structure, strengthening the original tooth. The repair looks as good as, or even better than, your original tooth. Such repairs can be used to restore small to large chips and other damage caused by decay or trauma.
Since the composite resin repair is applied directly to the tooth in the dental office, the repair can be made in a single appointment. You do not need to use a temporary repair while waiting for the final replacement to be made at a dental laboratory. This also means that the repair will cost less.
Another advantage of composite resin is that less of the healthy tooth needs to be removed to prepare the tooth to receive the replacement, since it bonds directly to the original tooth structure.
Porcelain veneers are very thin layers of tooth-colored porcelain that are also bonded to the tooth. They are usually recommended in situations with more serious injury or risk to the tooth, such as teeth that have been fractured, treated for root canal, or injured in contact sports.
Application of porcelain veneers may require more tooth preparation (in which more of the original tooth material must be removed) before the restoration can be bonded in position. Bonded porcelain veneers are likely to be longer-lasting than composite resins. They must be fabricated in a laboratory, so they require more than one visit and cost more.
All of the above are factors to consider in choosing composite resin or porcelain veneer to restore your chipped or damaged tooth. As usual in making such decisions, the final choice will depend on your individual situation.

If you engage in frequent air travel, you have probably experienced pain in your ears and sinuses related to pressure changes. The pain is caused by “barotraumas” (from baro meaning pressure — also the root of the word “barometer” — and trauma meaning injury) and is also called a “squeeze.” Divers also sometimes experience this discomfort or pain.
The cause of barotraumas is air pressure (or water pressure, in the case of divers) on the outside of your body that is not equal to the pressure inside your body. Normally when pressure outside your body changes, your organs such as your blood, bones, and muscles transmit the changes equally from outside to inside. Some structures in your body, such as your middle ear spaces and your sinus cavities (spaces in the facial bones of the skull), don't transmit the pressure as well because they are filled with air and have rigid walls. The maxillary (upper jaw) sinuses are pyramid-shaped spaces in the bone located below your eyes, on either side of your nose.
You have probably tried to stop such pain in your ears by yawning, chewing, or moving your jaw back and forth. These maneuvers, called “clearing,” allow air to move from the back of your throat into your ear canals so that the pressure can equalize. Similarly, your sinuses have small openings near their lower borders, so that you can clear pressure changes within them. If you have a head cold or flu and the membranes lining your sinuses are swollen and inflamed, they may close off the openings and make it difficult to clear these spaces. This can sometimes lead to intense pain.
Because the lower walls of these sinuses are adjacent to your upper back teeth, these teeth share the same nerves as the maxillary sinuses. This sharing sometimes causes pain felt in your back teeth to be perceived as pain in the sinuses, or vice versa. Pain felt a distance from its actual stimulus because of shared nerves is called “referred pain.”
Be sure to make an appointment with us if you experience pain in any of your teeth. Any defect in a filling or tooth can allow air to enter the tooth. It could be referred pain from your sinuses, or the result of pressure changes on trapped air within a filling or a tooth. Such pain, called barodontalgia (from baro meaning pressure, don't meaning tooth, and algia meaning pain) is an early sign of injury in a tooth.

Periodontal (gum) diseases are sometimes called “silent” because those who have them may not experience painful symptoms. But certain signs point to the existence of these common diseases. If you are experiencing any of the symptoms below, it is time to visit our office so these problems can be treated before they lead to serious infection and loss of teeth.
Gums that bleed during the brushing of teeth. Some people think that gums bleed from brushing too hard. In fact, healthy gum tissues will not bleed with normal brushing. The usual cause of bleeding gums is an accumulation of dental plaque in the areas where your teeth meet your gums. Plaque is a film of bacteria, called a biofilm, which accumulates on your teeth. If you are not brushing and flossing effectively, plaque irritates your gum tissues and causes an inflammation and swelling called gingivitis. This causes your gums to bleed easily on contact with a toothbrush or floss.
Gum tissues that appear red and swollen. If plaque is allowed to accumulate for 24 hours or more, the inflammation in your gum tissues becomes chronic. The continuous presence of bacteria makes it impossible for your body's natural defenses to fight the infection. Chronic inflammation leads to a breakdown of the normal attachment between the teeth and the gums, causing the formation of “pockets.” Inside these pockets the infection continues to attack the tissues that support your teeth. Eventually this can lead to a breakdown of the bone that surrounds your teeth.
Bad breath. Bad breath is another sign of accumulated plaque. The bacteria in plaque may emit gases that have an unpleasant odor.
Gums that are sensitive to hot or cold. Chronic inflammation can also cause the gums to recede, exposing the roots of the teeth in which nerves may be close to the surface, leading to sensitivity to heat and cold.
Teeth that are getting loose, or a painful area in the gums. If you experience these symptoms, the infection has progressed a long way from the “silent” stage. It is time to seek immediate professional help.
If you answered “yes” to any of the above questions, a professional dental examination is in order. With daily removal of plaque by effective brushing and flossing, along with frequent professional cleanings to remove any plaque that you were unable to catch, you will go a long way to preventing periodontal disease. Also, be aware that smoking tends to mask the effects of gum disease. Generally, if you smoke your gums will not bleed when brushing or flossing, nor will they show signs of swelling.
