The teeth of the upper and lower jaw should fit neatly together. When they don’t, it can increase the risk of tooth decay and gum disease. Orthodontics is an area of dentistry that diagnoses and corrects teeth and jaw alignment problems using devices such as braces and plates. 

When orthodontic treatment might be needed

Crooked, crowded and overlapping teeth can cause a range of problems, including: 

tooth decay and gum disease – teeth that are very close together can be harder to clean properly.A build-up of plaque can lead to tooth decay and gum disease

injury to the gum – if a tooth doesn’t meet with its partner on the opposite jaw properly, it may dig into the gum and cause damage

wear and tear – if teeth don’t sit properly the action of chewing can wear them unevenly

self-confidence – teeth problems can make people feel embarrassed and they may not feel comfortable to smile.
