Straight teeth are important for a number of reasons. Straight teeth have an impact on our oral health. Crooked or crowded teeth may contribute to food and plaque becoming trapped in hard to reach areas; this makes toothbrushing more difficult. Inadequate oral hygiene is the main cause of gum disease. Poor oral hygiene in conjunction with a sugary or acidic diet causes tooth decay. Both tooth decay and gum disease can result in dental pain and, if left untreated, tooth loss. Straight teeth also helps to boost self-esteem and confidence. Smiling makes us feel happier!
