Teeth whitening
There are several things that can affect the colour of your teeth. As we age, our teeth naturally tend to discolour over time. Everyday foods and drinks, such as coffee, tea, and red wine, are common culprits of tooth staining. Additionally, trending consumables like turmeric, acai bowls, green smoothies, and beetroot juice may also contribute to more frequent tooth discolouration.
At K Family Dental, we recommend ensuring your teeth are cleaned and your gums are in good health before undergoing a professional teeth whitening procedure. A dental cleaning removes plaque and surface stains, helping to achieve more uniform and predictable whitening results. By ensuring your teeth are properly cleaned beforehand, K Family Dental aims to provide you with an optimal whitening outcome.

What is the difference between bleaching and whitening your teeth?
Teeth that are whitened beyond their natural colour should be considered as bleached. The term bleaching refers to products containing bleaching agents, typically carbamide peroxide or hydrogen peroxide.
Whitening, on the other hand, restores the tooth’s natural colour by removing stains caused by diet or debris. Products like toothpaste, which clean the tooth’s surface, are technically considered whiteners, though their results may not compare to professional treatments.
At K Family Dental, during your dental whitening appointment, the treatment often involves enhancing the colour of your teeth beyond their natural shade using professional bleaching methods. Hydrogen peroxide is commonly used in such treatments, with concentrations typically ranging from nine to forty percent, depending on individual needs and suitability as assessed by your dentist.

Tooth discoloration and types of staining
Extrinsic Stains
Extrinsic stains develop on the outer surface of the teeth when particles from pigmented foods and drinks adhere to the enamel. Common offenders include beverages like coffee, tea, and red wine, as well as richly coloured sauces. Over time, these stains can deepen, becoming more difficult to remove without professional dental cleaning.Intrinsic Stains
Intrinsic stains occur beneath the tooth’s surface when pigment particles penetrate the enamel. Causes can include dental trauma, certain medications, or excessive fluoride exposure. While these stains are harder to address, professional teeth whitening, carried out by a dentist, can often reduce their appearance. However, results may vary depending on the individual case.Stains Caused by Ageing
Ageing combines both extrinsic and intrinsic factors, leading to noticeable tooth discolouration. Over time, the dentin beneath the enamel naturally becomes yellower, and the enamel itself thins, revealing the dentin more prominently. Lifestyle choices, such as smoking or consuming dark-coloured beverages, can further contribute to this change. Regular dental care and customised treatments can help manage these age-related changes effectively. -
What happens during a teeth whitening treatment?
If you opt for a teeth whitening treatment at K Family Dental, performed by a registered dentist, you can benefit from professional-grade care. During an in-office teeth whitening procedure, a regulated concentration of peroxide gel is carefully applied to the teeth by the dentist. Before the gel is applied, your gums are protected using either a physical rubber dam or a paint-on protective barrier to prevent irritation.
The peroxide gel is left on the teeth in intervals of fifteen to twenty minutes, with a total treatment time of up to one hour. For more persistent stains, additional sessions may be recommended. You may also be advised to use a dentist-prescribed at-home whitening kit to maintain and enhance the results.
How white can your teeth become?
Tooth whitening treatments can noticeably brighten the colour of your teeth. You can consult with a dentist at K Family Dental and review shade guides to discuss achievable results. On average, patients may notice an improvement of around two shades, though outcomes can vary significantly depending on factors such as enamel condition and the type of treatment used. Some individuals may achieve a brighter smile with up to nine or more shades of improvement, but results depend on individual circumstances and expectations.

My experience at K Family Dental was fantastic. I hadn't been to the dentist for some time and wasn't sure what to expect. Dr Chen was very friendly and took... Read More the time to explain to me why certain things were important (there was a lot I learnt during the visit). I also thought he was very thorough and was genuinely interested in my well-being. I'd definitely recommend his practice to others.
