Here at the Dental Surgery- St Marys we see a wide range of orthodontic issues. Some of these issues are genetic, and cannot be avoided, but others are caused by habits which have developed early in a child's life. Thumb sucking is an important coping mechanism for self soothing, and in itself is a learned developmental ability. However you can have too much of a good thing, and thumb sucking, if done for too long, can cause problems with the development of the jaws, palate and teeth.
Common problems include
* Bone and back teeth in a reverse relationship, known as a cross bite.
* opening of the front teeth by flaring forward, causing an increased overjet and an openbite
*narrowing and raising of the hard and soft palate
*a continuation of the tongue thrust swallowing pattern and inhibition of learning the mature swallowing pattern.
*speech impediments
*cracked, sore thumbs
*introduction of increased levels of bacteria in the mouth
When is a good time to stop?
The majority of children outgrow their habit on their own without any help from mum or dad. However some children continue to suck their thumb well after they start primary school. The recommended age to stop is at 3 years old, and even earlier is better if possible.
Some strategies to help kick the habit
Depending on the age and developmental stage of the child, different methods can be used to help stop their habit.
*In younger children who may not understand the reasoning of trying to stop their habit, substitution with another object to help them soothe with a blanket, stuffed toy can be effective.
*Removing any factors which may worry your child will help reduce their need to soothe (e.g. a nightlight if they are afraid of the dark)
*positive reinforcement is effective for older children, with rewards for observing behaviour you are encouraging. Having other family members or friends kindly remind the child when they slip up is also helpful.
*bitter tasting nail polish, mittens, shirts without arm sleeves for night time wear, and thumb guards can be used in combination with any other strategies.
If you feel your child needs a consultation for any potential jaw or teeth related issues, we at the Dental Surgery- St Marys would be delighted to see them.
