Your gums not only support and protect your teeth they also help present them in a visually attractive way. But some people’s gums seem to stand out too much — what’s commonly called a gummy smile — which diminishes their smile appeal. There’s no precise definition, but as a rule of thumb we consider a smile too gummy if four or more millimeters (about an eighth of an inch) of the gums show.
Fortunately, there are some techniques to improve a gummy smile. Which technique is best for you, though, will depend on why the gums are prominent — and causes vary. For example, you could have a gummy smile because your teeth appear too short compared to your gums.
Permanent teeth normally erupt to about 10 mm of visible length. But less than that, say 8 mm, could skew the visible proportion of gums to teeth too much toward the gums. Teeth can also appear shorter due to accelerated wear caused by grinding habits. Another cause could be the amount of upper lip rise when you smile. The lip may rise too high in a condition called hypermobility. This could reveal too much of the gums when you smile.
It’s important then to match the treatment to the cause. For example, we can enhance the appearance of shorter teeth through a surgical procedure known as crown lengthening.Â During this procedure a surgeon reshapes the gum tissues and underlying bone to expose more of the tooth’s length.
For upper lip hypermobility, we can restrict movement with Botox, a drug that paralyzes tiny parts of the involved muscles. This approach, though, will wear off in a few months — a more permanent solution is surgery to reposition the muscle attachments so as to prevent excessive movement.
If you’re concerned about a gummy smile, see us for a full examination and consultation. Once we know the reason why, we can offer a solution that will make your smile more attractive.

Although distressing to many parents, infants and toddlers sucking their thumb is a common if not universal habit. Most children phase out of it by around age 4, usually with no ill effects. But thumb-sucking continuing into late childhood could prove problematic for a child’s bite.
Thumb sucking is related to how young children swallow. All babies are born with what is called an infantile swallowing pattern, in which they thrust their tongues forward while swallowing to ensure their lips seal around a breast or bottle nipple when they nurse. Thumb-sucking mimics this action, which most experts believe serves as a source of comfort when they’re not nursing.
Around 3 or 4, their swallowing transitions to a permanent adult swallowing pattern: the tip of the tongue now positions itself against the back of the top front teeth (you can notice it yourself when you swallow). This is also when thumb sucking normally fades.
If a child, however, has problems transitioning to an adult pattern, they may continue to thrust their tongue forward and/or prolong their thumb-sucking habit. Either can put undue pressure on the front teeth causing them to move and develop too far forward. This can create what’s known as an open bite: a slight gap still remains between the upper and lower teeth when the jaws are shut rather than the normal overlapping of the upper teeth over the lower.
While we can orthodontically treat an open bite, we can minimize the extent of any treatments if we detect the problem early and intervene with therapies to correct an abnormal swallowing pattern or prolonged thumb sucking. For the former we can assist a child in performing certain exercises that help retrain oral and facial muscles to encourage a proper swallowing pattern. This may also help diminish thumb sucking, but we may in addition need to use positive reinforcement techniques to further discourage the habit.
To stay ahead of possible problems with thumb sucking or the swallowing pattern you should begin regularly taking them to the dentist around their first birthday. It’s also a good idea to have an orthodontic evaluation around age 6 for any emerging bite problems. Taking these positive steps could help you avoid undue concern over this common habit.

Watching your newborn develop into a toddler, then an elementary schooler, a teenager, and finally an adult is one of the most exciting and rewarding experiences there is. Throughout the years, you’ll note the passing of many physical milestones — including changes that involve the coming and going of primary and permanent teeth. Here are some answers to frequently asked questions about children’s dental development.
When will I see my baby’s first tooth come in?
The two lower front teeth usually erupt (emerge from the gums) together, between the ages of 6 and 10 months. But your baby’s teeth may come earlier or later. Some babies are even born with teeth! You will know the first tooth is about to come in if you see signs of teething, such as irritability and a lot of drooling. The last of the 20 baby teeth to come in are the 2-year molars, so named for the age at which they erupt.
When do kids start to lose their baby teeth?
Baby teeth are generally lost in the same order in which they appeared, starting with the lower front teeth around age 6. Children will continue to lose their primary teeth until around age 12.
What makes baby teeth fall out?
Pressure from the emerging permanent tooth below the gum will cause the roots of the baby tooth to break down or “resorb” little by little. As more of the root structure disappears, the primary tooth loses its anchorage in the jawbone and falls out.
When will I know if my child needs braces?
Bite problems (malocclusions) usually become apparent when a child has a mixture of primary and permanent teeth, around age 6-8. Certain malocclusions are easier to treat while a child’s jaw is still growing, before puberty is reached. Using appliances designed for this purpose, orthodontists can actually influence the growth and development of a child’s jaw — to make more room for crowded teeth, for example. We can discuss interceptive orthodontics more fully with you at your child’s next appointment.
When do wisdom teeth come in and why do they cause problems?
Wisdom teeth (also called third molars) usually come in between the ages of 17 and 25. By that time, there may not be enough room in the jaw to accommodate them — or they may be positioned to come in at an angle instead of vertically. Either of these situations can cause them to push against the roots of a neighboring tooth and become trapped beneath the gum, which is known as impaction. An impacted wisdom tooth may lead to an infection or damage to adjacent healthy teeth. That it is why it is important for developing wisdom teeth to be monitored regularly at the dental office.
