Teeth Whitening

As we age, pigments from food and drinks can gradually seep into the inner layers of our teeth, causing them to appear dull or discolored.
Teeth whitening is a safe and effective cosmetic treatment that can restore the natural brightness of your teeth—without any drilling or removal of tooth structure.
At Kamiyacho Dental Clinic, we offer an advanced whitening procedure using sodium polyphosphate, which minimizes sensitivity and does not require any post-treatment dietary restrictions.
In addition to whitening, our treatment reinforces tooth enamel by replenishing essential minerals—giving you a smile that’s not only whiter, but also stronger and more resistant to decay.
A radiant smile can do more than just enhance your appearance—it can boost your confidence and positively impact your overall well-being.
Our whitening treatment is part of a comprehensive approach to aging care, designed to help you maintain both a youthful look and long-term oral health.
Who Can Benefit from Whitening?
- You frequently drink red wine, coffee, or tea
- You’ve noticed your teeth becoming discolored with age
- You want whiter teeth without any drilling or filing
- You feel your complexion looks dull and want to brighten your smile
- Your teeth remain yellow despite regular brushing
What Makes Our Whitening Treatment Unique?
Achieve a visibly brighter smile in just one session.
A clean, white smile reflects intelligence and confidence—it also enhances your skin tone and leaves a positive impression.
At Kamiyacho Dental Clinic, we begin every case with a thorough consultation to understand your goals.
Whether you’re aiming for a Hollywood-bright smile or a naturally radiant look, we’ll tailor the treatment to suit your preferences.
Our whitening method uses a polynucleotide-based formula that not only whitens your teeth, but also strengthens them by restoring lost minerals.
The treatment is gentle, virtually painless, and safe for sensitive teeth.
Unlike conventional methods, our system requires no post-treatment restrictions on food or drinks, including red wine or curry.
The procedure is performed while you recline comfortably—many of our patients even fall asleep during the session.
When you wake up, your smile is already noticeably whiter, healthier, and more vibrant.
If you relate to any of the following concerns, whitening may be right for you:
・Your teeth have become yellow or dull over time
・Your skin tone looks less bright due to tooth discoloration
・Your teeth were darkened by medications like tetracycline in childhood
・You feel hesitant to smile due to the color of your teeth
・You’re looking for a whitening solution that also strengthens your teeth
Let us help you rediscover the confidence to smile freely.
Frequently Asked Questions
- How soon can I eat after whitening treatment?
- We apply a mineral-rich pack after treatment to help your teeth absorb essential nutrients. Ideally, you should wait about 30 minutes before eating or drinking, but eating immediately won’t cause harm.
Even richly colored foods and drinks—like red wine and curry—can be enjoyed on the same day.
- Will the treatment hurt?
- Most patients experience little to no discomfort.
In rare cases, if the whitening agent reaches exposed dentin or cementum through tiny enamel cracks, some sensitivity may occur. However, we carefully examine and protect these areas beforehand.
Mild sensitivity during or after the procedure is possible, but it usually fades within 24 hours.
- How white will my teeth get?
- Results vary based on your lifestyle, age, and the extent of discoloration.
During your consultation, we’ll discuss your habits and whitening goals to design a plan tailored to your needs. With consistent treatment, even yellowed teeth can return to a visibly brighter shade.
Note:
Teeth that have undergone root canal treatment or are affected by tetracycline staining may require more sessions. However, even these can be noticeably improved without drilling, and banding can be reduced.
- What’s the difference between in-office and at-home whitening?
- In-Office Whitening: Performed at our clinic using high-concentration whitening agents and light activation. You can achieve up to 7 shades lighter in a single session (results vary).
At-Home Whitening: Involves wearing a custom tray with whitening gel for 2–3 hours daily. Within 1–2 weeks, teeth typically lighten by 1–2 shades.
Even with home treatments, we recommend professional guidance to ensure safety and effectiveness.
- How long does whitening last?
- A single in-office session can keep your teeth bright for around 6 months. However, habits like smoking, coffee, and wine can gradually stain teeth again.
Ongoing care, such as home whitening touch-ups, helps extend the results.
Our unique method not only whitens but also strengthens enamel, promoting remineralization and helping your results last longer than standard treatments.
- Is whitening harmful to my teeth?
- Not at all. Our treatment strengthens rather than weakens your teeth.
By restoring minerals and reinforcing enamel, your teeth become healthier and smoother after whitening. Many patients report that their teeth feel cleaner and more polished.
You can include whitening as part of your regular oral care routine.

HYGIENE MANAGEMENT
徹底した衛生管理・ラバーダム防湿による再発防止への取り組み
根の治療は再発を繰り返すほどに治癒率が下がってしまうので、早期の治療の実施をおすすめいたします。
イニシャルトリートメント(最初に神経を治療する時)の確実性がその後の再発リスクに関わってきます。
神谷町デンタルクリニックでは以下のことを徹底して行っているため、
イニシャルトリートメントの場合(初めて神経を取る治療の場合)は1回、
再治療(他院で神経を取った歯の再発)の場合は治癒率向上のために2回で被せ物を装着することが可能です。
(歯根吸収が著しい、根の湾曲が大きい、以前の根管治療の金属片が深く刺さっている、などの難症例においてはこの限りではありません。)
また根の中を機械的に清掃していく器具などは、毎回新品を滅菌して使用しております。
