My tooth is starting to have a hole! It doesn't hurt, but should I mend this hole in the hospital? This tooth cavity is not very big.

Tooth decay has just begun: the initial tooth decay occurs on the enamel of the teeth, and there is no pain. The surface of the teeth is usually intact and there are no holes visible to the naked eye. Tooth decay in this area adjacent to the teeth is more difficult to find. Sometimes it takes x-rays to be sure.

Treatment: Dentists can apply high-concentration fluoride to the part with initial tooth decay, so that the initial decayed part can be restored.

Tooth decay spreads to ivory: there are cavities on the teeth, and eating will make you feel toothache.

Treatment: the decayed tooth is not big, and the tooth is filled when it is still strong.

If the scope of decay becomes extensive and the teeth are already very fragile, an artificial crown should be inserted.

Tooth decay spreads to the pulp: there are obvious cavities in the teeth, causing severe pain. Dental pulp may be infected by bacteria and die, and bacteria may even spread from dental pulp through root to nearby periodontal tissue, causing inflammation or abscess.

Treatment of dental caries

Before filling the hole in the tooth, local anesthesia can be given to the tooth if necessary to reduce the pain that may occur during the treatment. During the treatment, the dental caries were cleaned with high-speed and low-speed mobile phone drill needles, and then filled with composite materials. Due to aesthetic factors, composite resin is usually suitable for anterior teeth (Figure 6). Posterior teeth are usually filled with silver powder (Figure 7). Silver powder has been used in clinic for decades and is the most convenient, economical, safe and effective filling material. For aesthetic reasons, the posterior teeth can also be filled with composite resin (Figure 8). However, the application conditions of composite resin are strict, and not all teeth can be applied. When the cavities are too large and endanger the dentin of the residual teeth, crown cover (Figure 9) or cast metal crown or ceramic crown should be considered to restore the teeth to avoid the residual teeth from breaking.
