Thumbsucking is a natural reflex for children. Sucking on thumbs, fingers, pacifiers or other objects may make babies feel secure and happy and help them learn about their world.  Young children may also suck to soothe themselves and help them fall asleep.

How Can Thumbsucking Affect My Child's Teeth?

After permanent teeth come in, sucking may cause problems with the proper growth of the mouth and alignment of the teeth. It can also cause changes in the roof of the mouth.

Pacifiers can affect the teeth essentially the same ways as sucking fingers and thumbs, but it is often an easier habit to break.

The intensity of the sucking is a factor that determines whether or not dental problems may result. If children rest their thumbs passively in their mouths, they are less likely to have difficulty than those who vigorously suck their thumbs. Some aggressive thumbsuckers may develop problems with their baby (primary) teeth.

When Do Children Stop Sucking Their Thumbs?

Children usually stop sucking between the ages of two and four years old, or by the time the permanent front teeth are ready to erupt. If you notice changes in your child’s primary teeth, or are concerned about your child’s thumbsucking consult your dentist.

How Can I Help My Child Stop Thumbsucking?
​

• Praise your child for not sucking.
• Children often suck their thumbs when feeling insecure or needing comfort. Focus on correcting the cause of the anxiety and provide comfort to your child.
• For an older child, involve him or her in choosing the method of stopping.
• Your dentist can offer encouragement to your child and explain what could happen to their teeth if they do not stop sucking.

If these tips don’t work, remind the child of their habit by bandaging the thumb or putting a sock on the hand at night. Your dentist or pediatrician may prescribe a bitter medication to coat the thumb or the use of a mouth appliance.

Is the taste of ice cream or a sip of hot coffee sometimes a painful experience for you? Does brushing or flossing make you wince occasionally? If so, you may have sensitive teeth.

Possible causes include:

• Tooth decay (cavities)
• Fractured teeth
• Worn fillings
• Gum disease
• Worn tooth enamel
• Exposed tooth root

In healthy teeth, a layer of enamel protects the crowns of your teeth—the part above the gum line. Under the gum line a layer called cementum protects the tooth root. Underneath both the enamel and the cementum is dentin. 

Dentin is less dense than enamel and cementum and contains microscopic tubules (small hollow tubes or canals). When dentin loses its protective covering of enamel or cementum these tubules allow heat and cold or acidic or sticky foods to reach the nerves and cells inside the tooth. Dentin may also be exposed when gums recede. The result can be hypersensitivity.

Sensitive teeth can be treated. The type of treatment will depend on what is causing the sensitivity. Your dentist may suggest one of a variety of treatments:

• Desensitizing toothpaste. This contains compounds that help block transmission of sensation from the tooth surface to the nerve, and usually requires several applications before the sensitivity is reduced.
• Fluoride gel. An in-office technique which strengthens tooth enamel and reduces the transmission of sensations.
• A crown, inlay or bonding. These may be used to correct a flaw or decay that results in sensitivity.
• Surgical gum graft. If gum tissue has been lost from the root, this will protect the root and reduce sensitivity.
• Root canal. If sensitivity is severe and persistent and cannot be treated by other means, your dentist may recommend this treatment to eliminate the problem.

Proper oral hygiene is the key to preventing sensitive-tooth pain. Ask your dentist if you have any questions about your daily oral hygiene routine or concerns about tooth sensitivity.
