10 Causes Of Canker Sores
Reviewed: Dr. Gromatzky
Cause #4: Injury
An injury in the mouth can cause canker sores. The injury may arise as a result of biting your lip, cheek or tongue during a meal, sporting activity or a physical accident. Mouth injuries can also occur in the case of a person who has recently been fitted with orthodontic appliances for the treatment of dental conditions. This usually happens before the person gets used to having the appliances in the mouth.
To reduce your risk of getting injuries in the mouth, avoid hard crusted foods, wear a mouthguard during extreme sports and have orthodontic appliances fitted and adjusted professionally.
