The most important precautions after pulpitis treatment are: chew slowly when eating and drinking, and beware of damage to the teeth from too hard food for the following reasons: 1. Pulpitis can cause irrecoverable damage to the nerve of the tooth, and the treatment requires cleaning the root of the tooth and all the necrotic tissues within it, including the nerve. The tooth that loses the nerve loses its sensory ability, is insensitive to hard objects, and is prone to cracking when it gets high and bites hard objects; 2. When treating a tooth damaged by pulpitis, it is necessary to replace the damaged crown with a filling material, and its sensory ability is reduced.
