Is it good to file down teeth and wear braces?
When teeth suffer from decay, cracks, or deformities, grinding down the teeth and fitting braces may be beneficial. However, if tooth damage is minor, grinding down the teeth for braces might not be advisable. Specific details are as follows:

When teeth exhibit decay, cracks, or malformations, reducing tooth size and placing dental crowns can repair dental defects and restore normal tooth shape and function. This method is suitable for restoring anterior teeth such as incisors, improving dental aesthetics. For severely damaged teeth—for example, in patients with chronic periodontitis—reducing tooth size followed by crown placement helps protect the teeth and prevent further damage. Dental crowns also reduce the risk of tooth splitting or fracturing during use.
If tooth damage is minimal, grinding down the teeth involves an invasive and irreversible procedure that may damage the dental nerve, leading to spontaneous tooth pain, sensitivity to hot and cold stimuli, or nighttime pain. If porcelain-fused-to-metal crowns are selected, the metal component may react with the gums, causing gum discoloration and affecting appearance. Individuals without existing dental problems should not grind down their teeth for crowns, as this could interfere with normal dental tissue development and negatively impact overall health.
Patients should actively cooperate with their dentist's treatment plan and pay attention to maintaining good oral hygiene and adjusting dietary habits.
