Teeth Problems and Down Syndrome
Dental care is important for everybody, but people with Down syndrome can have a number of needs that require special attention.
What is different about the teeth of people with Down syndrome?
The teeth of people with Down syndrome, both baby teeth and permanent teeth, may come in late compared with children who do not have Down syndrome. On average, babies with Down syndrome get their first tooth at 12 to 14 months, but it may be as late as 24 months of age. Babies without Down syndrome usually get their first teeth between 6 and 12 months. It is typical that a child with Down syndrome may not get all 20 baby teeth until he or she is 4 to 5 years old, rather than 2 to 3 years old (which is typical for kids without Down syndrome). The front permanent teeth and permanent 6-year-old molars may not erupt until the child is 8 or 9 years old. It is also common for the teeth of kids with Down syndrome to erupt in a different order than it does in kids without Down syndrome.
Small and Missing Teeth
Frequently, people with Down syndrome have smaller than average teeth, as well as missing teeth. It is also common for the teeth of people with Down syndrome to have roots that are shorter than average.
People with Down syndrome may have large tongues, or they may have an average-size tongue and a small upper jaw that makes their tongue too large for their mouth. It is also common for people with Down syndrome to have grooves and fissures on their tongues.
Problems With Bite
People with Down syndrome may have small teeth, which can cause spacing between the teeth. They also tend to have a small upper jaw. This may cause crowding of the teeth and may result in the permanent teeth being impacted because there is no room in the mouth for them to come in. When the upper jaw is smaller than usual, the top teeth may not go over the bottom teeth the way they are meant to; instead, the bottom teeth may extend farther out than the top teeth. It is also common that the front teeth of people with Down syndrome do not touch in front.
Orthodontics (braces) may be able to improve some of these issues. Orthodontics requires a lot of cooperation and makes the teeth even more difficult to keep clean, so it may not be possible in all people, or it may be a good idea to wait until a child is older and able to tolerate it fairly well. Having orthodontic appliances in the mouth can also pose challenges to speech. Children without Down syndrome typically adapt their speech quickly; however, in a child with Down syndrome, for whom speech may already be an issue, adapting to the appliances can be very difficult. It may therefore be a good idea to delay orthodontic treatment until a child is older and her speech is further along.
Tips to Prevent Gum Disease and Cavities
People with Down syndrome are at an increased risk for gum disease (periodontal disease). Even when they do not have a lot of plaque and tartar (calculus), people with Down syndrome get periodontal disease more frequently than others do. This is because people with Down syndrome have an impaired immune system and do not have some of the natural protections against gum disease. To prevent gum disease, brush twice daily, focusing the bristles along the gum line. Also floss daily, and be sure to visit the dentist regularly to have gum health monitored and to have X-rays taken to monitor bone levels. If the gums bleed, that means that they are inflamed. Do not stop brushing and flossing, though, even if the gums are inflamed. In fact, brushing and flossing will keep the gums clean and help minimize the inflammation.
Some research says that people with Down syndrome are at less of a risk for cavities; however, much of that research was done when people with Down syndrome lived in institutions and had very restricted diets. People with Down syndrome do get cavities, so brushing with fluoride toothpaste, flossing between any teeth that touch, and limiting the consumption of sugar and refined carbohydrates will help prevent cavities.
What can I do to prevent cavities and gum disease?
-- Brush teeth twice daily with a soft toothbrush and fluoride toothpaste. Children younger than 2 should get a thin smear of fluoride toothpaste, and children 2 to 5 years old should get a pea-size amount.-- Limit the frequency of sugar, and cracker- and bread-based snacks.-- The first dental visit should be within 6 months of the eruption of the first tooth, or by 1 year of age.-- Visit the dentist regularly, typically every 6 months (although some people may need to go more often).
How do I find a dentist?
For children, the American Academy of Pediatric Dentistry website can be a useful tool to find a dentist. Pediatric dentists have 2-3 years of education after dental school in the care of children, including kids with special needs such as Down syndrome.
For adults, general dentists' comfort levels with some of the unique needs of people with Down syndrome may vary. A general dentist who has completed a general practice residency, 1-2 additional years after dental school, has extra training in caring for patients with disabilities. The Special Care Dentistry Association is a resource to find a dentist experienced in treating people with Down syndrome.
You can call your local dental school and they will typically have residents or faculty who are experienced in caring for people with Down syndrome.
Some hospitals have dental departments and these dentists are typically trained in caring for people with Down syndrome as well.
What if I do not think my child can cooperate for dental care?
Pediatric dentists are experienced in working with children of all ages and children who have different abilities to cooperate. Pediatric dentists have many skills to help children have a successful dental visit. Some children who need dental treatment, may need some form of sedation. Your dentist will be able to discuss this with you depending on your child's dental needs and medical conditions.
Do People with Down Syndrome Need to Take Antibiotics Before Going to the Dentist?
People who have, or have had, certain kinds of heart defects need to take antibiotics before their dental appointment. Ask your physician or cardiologist if antibiotics are needed and be sure to inform your dentist of all health conditions, including heart issues.
What can I do about my child grinding his or her teeth?
It is very common for children to grind their teeth. Typically it does not cause dental problems, and children tend to grow out of it on their own. However, sometimes, children with neurological disabilities do not outgrow it or they do it so severely that it causes damage to the teeth. A dentist can examine your child's teeth to ensure that the grinding is not causing any problems. Typically, mouthguards are not made for children who grind their teeth, because the risk of the child choking on the mouthguard if it breaks is too great.
