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.
However, after the 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.
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.
Tips for helping your 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 the above 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.

Rather than soothe and comfort, a hot cup of tea or cocoa can cause people with sensitive teeth a jolt of pain. But scientists are now developing a new biomaterial that can potentially rebuild worn enamel and reduce tooth sensitivity for an extended period. They describe the material, which they tested on dogs, in the journal ACS Nano.
Chun-Pin Lin and colleagues note that tooth sensitivity is one of the most common complaints among dental patients. Not only does it cause sharp pains, but it can also lead to more serious dental problems. The condition occurs when a tooth's enamel degrades, exposing tiny, porous tubes and allowing underlying nerves to become more vulnerable to hot and cold.
Current treatments, including special toothpastes, work by blocking the openings of the tubes. But the seal they create is superficial and doesn't stand up to the wear-and-tear of daily brushing and chewing. Lin's team wanted to find a more durable way to address the condition.
The researchers made a novel paste based on the elements found in teeth, namely calcium and phosphorus. They applied the mixture to dogs' teeth and found that it plugged exposed tubes more deeply than other treatments. This depth could be the key, the researchers conclude, to repairing damaged enamel and providing longer-lasting relief from tooth sensitivity.
