If you are dissatisfied with the way your smile looks, and your dentist is unhappy with the way your teeth fit together — but you don't like the idea of wearing braces — clear aligners may be your best solution. How much do you know about this teeth-straightening alternative? Below are some FAQs on the subject.

What do we mean by clear aligners? Clear aligners are a system for straightening teeth that uses clear plastic removable “trays” that fit over your teeth. As the teeth move to fit the trays, new trays are substituted that are designed to continue to move your teeth into the desired position. This system is an alternative to the traditional system of brackets and wires known as braces.

How can teeth be moved to new positions? The connection that holds a tooth in place in your jaws — the periodontal ligament — is not immobile. It constantly changes its position based on the normal forces of your bite. As the ligament is pushed on one side and pulled on the other, the living cells of your mouth respond by depositing bone and cementum (the protective covering of the tooth's root) on one side and dissolving it on the other. Normally this happens in a balance, maintaining your teeth in their position. We can manage these slight changes by applying constant light forces to move teeth in a predictable way.

How long does it take to move teeth to their optimum position using clear aligners? As with braces, the process is gradual. Total treatment time can range from six months to two years.

Do the trays have to be worn all the time? As you move through the sequence of trays, each is worn for 20 hours per day for two weeks. They may occasionally be removed for important social occasions.

How does an orthodontist design the sequential trays that are used? The trays are designed using a computer, based on an assessment and images of your mouth, teeth and jaws.

What kinds of problems can clear aligners correct? This method works well to correct mild to moderate crowding or spacing. If your back teeth already fit together as they should, the system may be ideal. If you have an extreme overbite or underbite, braces might work better.

Are clear aligners an alternative for everyone? Clear aligners are recommended for adults and recently, teenagers. They are not usually recommended for young children.

Why is it important to have your teeth straightened? Besides the obvious benefit of feeling better about yourself and your appearance, straight and well-aligned teeth work better. You will experience a better-functioning bite and can improve your oral health.

At some point in every person's life, they will experience bleeding gums or gingivitis, a mild inflammation of the gingiva (gums), which is the first stage of periodontal (gum) disease. For example, when was the last time you were brushing or flossing your teeth and noticed that your gums were bleeding or that when you spit and rinsed there was some blood? When this occurs, it is a sign that you have gum disease, as healthy gum tissues do not bleed. And no, it is highly unlikely that your bleeding is from brushing too hard. You would have to use extreme force to make healthy gum tissues bleed. However, this is exactly how most people discount or ignore this warning sign.

If this sounds like you or another member of your family, here's what you can expect when you see us for treatment. Depending on the severity of your periodontal disease, all of these treatment options may not be necessary.

Behavior change: We will collect a thorough medical history to obtain facts about your oral hygiene, eating and other personal habits such as alcohol and tobacco use to determine their impact on your periodontal disease. Proper brushing and flossing techniques are necessary for everyone, whether you have early or late stage gum disease; however, you must commit to a good daily oral health routine if you want to achieve success and thus keep you mouth and teeth healthy.

Calculus (tartar) removal: Cleaning is not just your responsibility. We'll clean and polish your teeth to remove calculus (tartar), the calcified deposits of bacterial products that become glued to the teeth and roots that you can’t remove. In fact, routine visits to see us for a thorough cleaning will help ensure that all the unhealthy calculus (tartar) is removed from your teeth.

Evaluation: Usually after three or four weeks, we will want to see you to evaluate your progress and to see the response of your gingival tissues to the treatment thus far. And depending on the severity of your gum disease, we may need another follow-up exam to decide the best maintenance and monitoring regimen necessary to keep your mouth healthy.

Occlusal or Bite Therapy: This treatment, if necessary, usually occurs once your gum tissues have been stabilized and the inflammation and infection have been controlled. It is during this phase that we will address loose teeth or teeth that have shifted or drifted in position.

Surgical Therapy: For more severe cases of gum disease, you may need periodontal plastic surgery to repair and regenerate gum and bone tissue and their attachment to the teeth. It may also be necessary to replace missing teeth with dental implants.

If you are ready to talk to us about the current state of your mouth (or the mouth of another member of your family), contact us today to schedule an appointment. The first step towards achieving optimal oral health could start with this simple call. Or, you can learn more by reading, “Understanding Gum Disease.”

What is composite resin bonding?
This term refers to a kind of tooth-colored material that is a mixture of a plastic resin and a glass filler. The glass gives the mixture, or composite, strength and translucency that is similar to a natural tooth. The composite is bonded to the tooth by slightly abrading or roughening the tooth so that the resin fills in small cuts in the tooth surface and bonds with it. The end result functions and looks like part of the original tooth.

What is bonding used for?
This technique is a good way to restore chipped or stained teeth or to change a tooth's shape or color. It can also be used to restore parts of a tooth near the gum line where the gums have receded and left the root partially exposed.

What are the advantages of bonding?
Composite resin tooth restorations have several advantages.

• They take only a single dental visit because they are done right in the dental chair rather than having to be sent to a dental lab for preparation.
• They are less expensive than many other dental restorations.
• They leave most of the original tooth intact since little tooth preparation or drilling has to be done in order to make the composite material bond to the tooth.
• They can be made in a wide range of colors and can be matched well with the teeth around them.
• Because little of the original tooth has to be removed, they are a good choice for teens, whose dental arches (upper and lower jaws) are still developing.

What are the disadvantages of bonding?
The composite resin material is not as strong as the original tooth material, so the bonded restorations may not last over a long time. If it does last, the material may also stain as it ages.

When should you choose bonding?
Composite resin bonding is a good choice for a quick and attractive tooth restoration that may be replaced later by something more permanent, such as porcelain veneers.

The term “root canal” strikes fear into many dental patients. But rest assured that this procedure is the best solution to many severe dental problems. It can be pain-free and will actually relieve pain and suffering from infections and dental injuries.

Why would you need root canal treatment? This procedure becomes necessary when the pulp, the nerve tissue on the inside of a tooth's root, becomes inflamed or infected because of deep decay, or when it has suffered a severe injury as a result of an accident or blow to the mouth. The pulp is composed of living tissues including nerves and blood vessels.

Root canal treatment may be necessary if you have a wide variety of signs or symptoms. The pain can feel sharp or intense when biting down, or linger after eating hot or cold foods. Sometimes it can be a dull ache or there may be tenderness and swelling in your gums near the site of the infection.

After trauma, the pulp of a tooth can be exposed or damaged because a tooth has fractured or cracked, necessitating root canal treatment. And the procedure is often needed for permanent teeth that have been dislodged or knocked out.

What exactly is root canal treatment? Root canal treatment is also called endodontic treatment, from the Greek roots “endo” meaning “inside” and “odont” meaning “tooth.” During the procedure, the area is numbed to relieve pain. A small opening is created in the chewing surface of the tooth and very small instruments are used to remove dead and dying tissue from the inside. The pulp is needed during a tooth's growth and development, but a mature tooth can survive without it. The canal is disinfected and then sealed with filling materials. Sometimes root canal specialists use microscopes to work at an intricate level of detail on these tiny areas of the tooth's root.

By having root canal treatment, you prevent inflammation and infection from spreading from the root of a particular tooth to other nearby tissues. Infection can result in resorption, an eating away of the root and its anchoring bone, and you could lose your tooth or teeth. So please don't hesitate when we recommend this treatment. It's not as bad as you think, and you will feel significantly better afterwards.
