Though thumb sucking is normal for children, when their permanent teeth start to come through, this can cause problems. When kids suck their thumbs, fingers or dummies this can cause their permanent teeth to misalign, which can cause issues.
We recommend that if your child is still sucking their thumb by the age of six, then gently encourage them to stop with positive reinforcement techniques. If you are having any issues, our dentists will be able to suggest some positive methods to encourage your child to stop.
