Think you’re too old to have your teeth straightened? In reality, healthy teeth can be moved at any age to better positions. For the many adults who have some form of malocclusion (bad bite), orthodontics is still a viable option even in later years.
As important as it is to self-image and confidence, treating misaligned teeth can benefit you more than just improving your smile. Misaligned teeth may be harder to keep clean, setting up a mouth environment advantageous to the development of tooth decay or periodontal (gum) disease, the risks of both rising with age. And normally aligned teeth are easier to chew with than those misaligned.
Age isn’t the determining factor for whether you’re a good candidate for orthodontics — but your dental health is. Gum disease in particular can cause supporting bone loss, which can complicate orthodontic treatment. It’s important then that we first perform a complete oral examination and attempt to treat problems such as decay or gum disease first before attempting tooth movement.
What type of orthodontic treatment you’ll need will depend on the type of malocclusion you have and its relationship to the way your jaws fit together. Because your adult jaws have fully developed you may need orthognathic (“jaw straightening”) surgery to address certain advanced forms of malocclusion. If your bite problems aren’t that severe (the majority of situations) they can be treated with braces or, an increasingly popular alternative, clear aligners. These customized clear plastic trays are nearly invisible compared to metal braces and are effective for most patients.
Following the completion of tooth movement and other bite procedures, you will most likely need to wear a retainer to help prevent the teeth from reverting to their older positions. You may need to wear the retainer for a longer period than a younger patient, or perhaps indefinitely. Even with this mild inconvenience, though, you’ll still experience the positive effects of healthier and better functioning teeth and a great new smile.

A “gummy” smile, in which the upper gums are too prominent, is a common condition. There are several causes for gummy smiles — determining which one is the first step to having your appearance changed.
Although perceptions vary from person to person, most dentists agree a gummy smile shows 4 mm or more of gum tissue, and the amount is out of proportion with the length of the crown (the visible tooth). Teeth normally erupt through the gums during childhood and continue development until early adulthood, shrinking back from the tooth until stabilizing in place.
This typically produces a crown length of about 10 mm, with a “width to length” ratio of about 75-85%. But variations can produce differences in the relationship between teeth and gums and the width to length ratio of the teeth. The teeth may appear shorter and the gums more prominent. Worn teeth, caused by aging or grinding habits, may also appear shorter.
If tooth to gum proportionality is normal, then the cause may be upper lip movement. When we smile, muscles cause our lips to retract 6-8 mm from the lip’s resting position. If the amount of movement is greater (meaning the lip is hypermobile), it may show too much of the gums. The upper jaw can also extend too far forward and cause the gums to appear too prominent.
There are a number of ways to improve gummy smiles, depending on the cause. Periodontal plastic surgery known as crown lengthening removes and reshapes excess gum tissue to reveal more of the tooth. Lip hypermobility can be reduced with Botox injections (to paralyze the muscles) or in some cases with surgery to reposition the muscle attachments. Orthognathic surgery can be used to surgically reposition an overextended upper jaw. Other cosmetic enhancements such as orthodontics, bonding or porcelain restorations can also prove effective.
The first step is to obtain an accurate diagnosis for your gummy smile. From there, we can devise the best treatment approach to bring your smile back into a more attractive proportion.

Winter is the time for snowy landscapes, hot cocoa and flannel PJs, but for some 'tis the season for tooth trouble. What can you do to keep your teeth from becoming a pain this winter?
Tackle tooth sensitivity. Does crisp winter air on your teeth give you a jolt? A study published in the Journal of the American Dental Association found that 1 in 8 people (over 12%) suffer from tooth sensitivity, particularly to cold. Sensitivity can result from receding gums, erosion of tooth enamel, tooth decay or other dental problems. If you experience tooth sensitivity, use toothpaste that is specially formulated for sensitive teeth and breathe through your nose to protect your teeth from extreme cold. Most importantly, schedule a dental exam to determine why your teeth are sensitive.
Stay hydrated. In winter, we spend more time with the heat on and we tend to drink less water. A dry mouth can result, which can lead to bad breath, tooth decay and gum disease. Staying well hydrated keeps your gums and teeth moist and helps you produce more saliva, which is key to good oral health and fresh breath. Saliva helps wash away food debris and bacteria, neutralize decay-causing acid and repair weakened tooth enamel. For healthy teeth and gums, be sure to drink plenty of water this winter.
Safeguard your teeth on the slopes. Are you planning to hit the slopes this winter? Be sure to wear a mouthguard to help protect against injury. Beginning skiers and snowboarders are more likely to suffer falls that could result in dental injuries, while experts may fly over bumps and jumps, causing the upper and lower teeth to knock together with force. Even backyard sledders are at risk of dental injury. Mouthguards help protect against chipped, broken, or knocked-out teeth as well as soft tissue damage. So before you enjoy wintertime sports, make sure your teeth are protected. For the best fit and comfort, ask us about a custom mouthguard.
