The clinic specializes in dentistry and pediatric dentistry, offering treatments including general dentistry (cavities, periodontal disease, dentures), cosmetic dentistry, pediatric dentistry, and oral surgery.

Last appointments are accepted until 6:00 PM on weekdays and 5:30 PM on Saturdays. The clinic is closed on Thursdays, Sundays, and public holidays. Special attention is paid to anesthesia procedures to minimize discomfort. The clinic applies surface anesthesia gel before needle insertion, uses fine needles, and warms anesthesia solution to 37°C to reduce body temperature shock. Techniques include slow injection, electric anesthesia injectors for controlled dosage, inserting needles in less sensitive areas, and administering medication through gum vibration without needle movement, all aimed at reducing patient burden.
