Otake Dental Clinic is a dental clinic located in Kawakita-cho, Seto City, Aichi Prefecture. The clinic offers two whitening methods for patients concerned about tooth discoloration: office whitening and home whitening. Office whitening involves applying a special gel to the teeth at the dental clinic and irradiating with light to whiten the teeth in approximately 1-2 hours. Home whitening involves creating custom-made mouthpieces based on the patient's dental impressions and wearing them at home for about 2 hours daily for approximately 2 weeks, with the feature of being inconspicuous to others due to the transparent mouthpieces. The clinic also recommends dual whitening, which combines both methods for more natural whitening results. Regardless of the method chosen, an oral examination is performed first, and if treatment for cavities or other issues is required, it is completed in advance. Before whitening, PMTC removes plaque and tartar that cannot be removed by brushing, ensuring treatment begins in a clean state. In terms of facilities, in addition to multilingual support including English and Korean, credit cards and electronic payments are accepted, and parking and barrier-free facilities are available.
