Located in front of Yokohama Station, this clinic specializes in aesthetic dentistry. Whitening and cleaning serve different purposes: whitening primarily aims to bleach and whiten overall tooth discoloration, while cleaning removes tartar and other deposits to prevent periodontal disease. The clinic combines whitening and cleaning to achieve smooth, beautifully white teeth, and also offers cleaning-only treatments. Whitening involves 1 to 3 light exposures per visit, with frequency and number of sessions adjusted based on original tooth color, age, and desired whiteness level. For first-time visits including consultation, treatment takes approximately 20 minutes for one LED light exposure, 30 minutes for two, and 40 minutes for three. No significant risks or side effects have been reported, though pain similar to tooth sensitivity may occur if cavities or small cracks are present in the treated area; this typically subsides within 1-2 hours, and at most within 24 hours. Due to their proprietary coating, there are no dietary restrictions after treatment, allowing consumption of coffee, red wine, curry, and other foods and drinks. Treatment is not possible for those with front orthodontic appliances, but those with lingual braces can receive treatment. English support is available, and credit cards, debit cards, and electronic payments are accepted.
