Cosmetic Dentistry FAQ
Cosmetic dentistry includes treatments designed to improve the appearance of the teeth and smile. Tooth whitening can lighten natural teeth, while dental implants can replace missing teeth. Results, suitability and risks vary between patients, so treatment should always follow an appropriate dental assessment. Whitening is not permanent and restorations such as crowns, veneers and implants will not whiten.
Q: How does tooth whitening work?
A: Professional tooth whitening usually involves a peroxide-based bleaching gel. Dentist-prescribed home whitening commonly uses custom-made trays that fit over the teeth. The bleaching agent penetrates the tooth and lightens discolouration. You can read more in the NHS guide to teeth whitening.
Q: How long does tooth whitening last?
A: Tooth whitening is not permanent. According to current NHS guidance, the effect may last for around three years when patients follow their dentist’s advice. Smoking and regularly consuming staining drinks such as tea, coffee and red wine may cause teeth to darken again. Any maintenance or top-up whitening should be discussed with your dentist.
Q: Who can benefit from tooth whitening?
A: Many adults with healthy natural teeth and gums may be suitable for whitening, but a dentist should assess you first. Whitening only changes the colour of natural teeth, so crowns, veneers, dentures, fillings and dental implants will not whiten in the same way. Some types of discolouration may also respond differently to treatment.
Q: Is tooth whitening safe?
A: Tooth whitening can be safe when it is prescribed following an assessment by a registered dentist and provided by an appropriately registered dental professional. The General Dental Council guidance on tooth whitening explains who can legally provide whitening treatment in the UK.
Q: Are there any side effects?
A: Some patients experience temporary tooth sensitivity, particularly to cold food and drinks. Whitening gel can also irritate the gums if it comes into contact with them. These effects are usually temporary, but patients should speak to their dentist if symptoms are severe or persistent.
Q: How do I find the right dentist?
A: Choose a dentist who is registered with the General Dental Council and who will examine your teeth and gums before recommending whitening. Dentists like the Smiles Studio near Southampton offer the full range of whitening treatments.
Q: Do I brush my teeth as usual during treatment?
A: Yes. Continue maintaining good oral hygiene throughout whitening treatment and follow the specific instructions provided by your dentist. Dentist-prescribed trays and gels should only be used in the way you have been instructed.
Q: Should I avoid food and drink after treatment?
A: Your dentist may recommend avoiding or limiting strongly coloured foods and drinks during the whitening process because they can contribute to staining. Leeds Teaching Hospitals NHS Trust advises patients undergoing whitening to consider avoiding foods and drinks such as red wine, curry and tomato-based products. See its tooth whitening information for adult patients.
Q: Should I avoid smoking during tooth whitening?
A: Smoking can stain teeth and has wider effects on oral and general health. Avoiding smoking can help maintain the appearance of whitened teeth and benefit your overall oral health.
Q: Can crowns, veneers or implants be whitened?
A: No. Whitening treatments lighten natural tooth structure but do not change the colour of existing crowns, veneers, fillings, dentures or dental implant restorations. Your dentist can discuss alternative cosmetic options if existing dental work no longer matches the shade of your natural teeth after whitening.
Q: What are dental implants?
A: Dental implants are used to replace missing teeth. An implant is placed into the jaw and can support a crown, bridge or denture depending on the patient’s needs. Suitability depends on factors including oral health, bone levels and the number and position of missing teeth.
