Teeth Whitening

Yes, professional teeth whitening is safe when carried out after an oral assessment and under the supervision of a qualified dentist.

• Food & Drinks: Coffee, tea, red wine, cola, and strongly coloured foods can gradually stain the teeth.

• Smoking & Tobacco Use: Nicotine and tar can cause yellow or brown stains on the enamel.

• Poor Oral Hygiene: Infrequent brushing or not flossing can lead to plaque buildup, which attracts stains.

• Ageing: Over time, enamel wears down, revealing more of the yellowish dentin beneath.

• Medications: Some antibiotics and mouthwashes can discolour teeth, especially if used long-term.

• Dental Trauma: Injuries to a tooth can cause internal staining.

Some patients may experience temporary sensitivity during or after treatment, but this usually fades within one to two days. At Angel Smile, we also offer a sensitive formula and recommend desensitizing toothpaste if needed to keep you comfortable.

Yes, you can still whiten your teeth if you have crowns, fillings, or other dental restorations. However, it's important to know that whitening treatments only work on natural tooth enamel — they won't change the colour of crowns, fillings, veneers, or bridges.

During you assessment, we’ll assess your smile and discuss the best approach to ensure a natural, even result. In some cases, you may choose to update older restorations after whitening to match your brighter smile.

Whitening results can last anywhere from 6 months to 2 years, depending on your lifestyle and diet. Avoiding staining foods and drinks such as coffee or red wine, along with maintaining good oral hygiene, will help keep your smile brighter for longer.

With custom-made home trays from Angel Smile, you can also easily top up your whitening to maintain your results for many years.

No. Whitening under professional supervision does not harm enamel.
