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.

While some people associate the need for root canal treatment with an injury or trauma to a tooth (which is a valid cause), it can also most commonly be caused by tooth decay that is left untreated. This is the reason why we have put together this brief guide to explain the three common stages of tooth decay that lead up to the need for a root canal.

Stage 1: During this stage, decay begins to form in the tiny grooves on the biting surface of a tooth or where the teeth contact each other. The result is loss of the surface enamel of the tooth.

Stage 2: Left untreated, the disease progresses through the enamel and into the dentin, which forms the body of the tooth. Once in the dentin, it progresses more rapidly until it reaches the pulp — the living tissue within the root canals of the tooth. The decay infects the pulp tissues, which contain the nerves of the teeth, causing pain. The end result of inflammation and infection of the pulp is that it dies.

Stage 3: As the nerve dies an infection results, which causes pain and swelling. For some people who do not regularly visit our office, this may be the first physical sign that they have a problem. But all is not lost, a successful root canal treatment, whereby the infected pulpal tissue is removed and the root canals are cleaned and sealed will not only relieve the pain, but save your tooth. So the good news is that once a tooth has had the appropriate endodontic treatment (“endo” – inside; “dont” – tooth) followed by a proper restoration, the tooth can last as long as your other teeth. The key is to take proper care of your teeth, have routine cleanings, and visit our office as soon as you feel you have a problem with a tooth.

If you are having pain or symptoms from a tooth or teeth, check it out with us — you may or may not need a root canal treatment. Contact our office to schedule an appointment and find out. Don't wait until it's too late. And to learn more about the signs, symptoms, and treatments for a root canal, read the article “I'd Rather Have A Root Canal....”

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.

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.
