If you have a cracked tooth
A cracked tooth can be extremely painful and it is one of the difficult tooth issues to diagnose. Most of the time the only sign a cracked tooth shows is the sudden pain when you bite down. If you start to feel pain when you eat, first check for where the pain is coming from, then immediately visit your dentist and point it out to them. Your dentist will use a special bite stick to determine if there is a fractured root. The stick can help identify the exact point when you apply pressure.
Your dentist may also conduct a dental x-ray to identify severe fractures. Although it may be more difficult to detect the hairline fracture. For this, your dentist will perform a special diagnostic test. Immediate treatment of your cracked tooth [3] is very important to avoid complications such as tooth decay.
