1. Dental decay
If you do not practice good oral hygiene after getting a crown, plaque may accumulate at the margin where the crown and the tooth meet. Though the crown cannot decay, your tooth still can.
The best remedy for this is to brush and floss your teeth twice daily. If you already have a small decay in an accessible area, the doctor can place a filling. However, if the decay is underneath the crown, the doctor will need to take off the dental crown, remove the decay, place a new core, and make a new dental cap. Since the cost of a dental crown is quite high, it is better and cheaper to take care of your teeth to prevent dental decay.
2. Sensitivity and discomfort
In the days after having your crown installed, you may notice that your teeth are sensitive to hot or cold foods. This often happens when the tooth enamel is trimmed away during the crowning process and the dentin is exposed. This means that the crown does not completely cover your tooth.
If this is the case, your dentist can apply a solution to the crowned tooth to protect the exposed dentin from temperature changes. He/she may also advise you to use toothpaste designed for sensitive teeth.
