Dentistry techniques encompass a variety of methods used to diagnose, treat, and prevent oral health issues. Common techniques include teeth cleaning, fillings for cavities, and root canals to treat infected teeth. Dentists also use X-rays to identify problems beneath the surface and sealants to protect teeth from decay. Advanced techniques in dentistry may involve laser treatments for gum disease or cosmetic procedures like teeth whitening and veneers. Additionally, orthodontics focuses on correcting misaligned teeth using braces or clear aligners. These techniques aim to improve both the function and appearance of patients' smiles.
