Teeth Whitening

If you feel that your smile has been lacking in sparkle and shine, perhaps it is time to consider teeth whitening.

Teeth whitening is a standard cosmetic procedure that is conducted in dental clinics worldwide, including in Singapore. This procedure helps one to improve the colour of their teeth and brighten their overall smile.

There are several factors that contribute to tooth discolouration, including smoking or drinking beverages that can stain the teeth, such as tea and coffee. With tooth whitening, your teeth will be able to regain its shine, giving you your pearly whites back.

Tooth whitening involves the bleaching of yellow, discoloured teeth with bleaching agents. Such whitening solutions will penetrate the porous enamel layer of every tooth. After which, an activator (typically a source of light or heat) will be used to start an oxidation reaction, resulting in the whitening of the teeth.

It is worth noting that not all stains can be removed through the use of teeth whitening techniques. Understanding the different types of tooth stains will help you determine the right treatment that best addresses your dental condition. Besides, these treatments have different price points; so if you’re working on a budget, you’ll want to know your viable options.

Extrinsic Tooth Stains

Just as the name suggests, extrinsic tooth stains are stains that affect the enamel layer of the tooth. The stains are typically the result of consumption of dark coloured foods and beverages, or tobacco use.

Extrinsic tooth stains can easily be removed through scaling and polishing.

Intrinsic Tooth Stains

Unlike extrinsic tooth stains, intrinsic tooth stains are stains that are located deep within the tooth. These stains are comparatively much harder to remove as they are typically not receptive to teeth whitening treatment. Common causes include medication, tooth decay and trauma to the tooth, amongst many other things.

Since regular teeth whitening techniques cannot treat these intrinsic stains, your dentist may suggest an alternative solution, such as dental veneers to cover and conceal these stains.

Age-Related Stains

As with any parts of the body, the enamel layer of the teeth will thin out due to wear and tear, and age. This results in teeth starting to discolour into a light shade of yellow.

Depending on the type of tooth stains (whether it’s intrinsic or extrinsic), those that suffer from age-related tooth stains can benefit from teeth whitening treatments.

Usually, dentists will apply peroxide (either hydrogen or carbamide) for teeth whitening. The bleaches break the stains into smaller parts, making the colour less concentrated. In turn, it makes your teeth whiter. At BigSmile, our doctor can use a higher percentage of peroxide safely to give your teeth an even brighter result!

When done by a professional, teeth whitening can potentially help teeth become whiter by approximately six or seven shades. However, how effective it will be specifically will still depend on the original status of the teeth.

Regardless, undergoing professional teeth whitening in Singapore can make teeth look the whitest shade possible for most circumstances.

Teeth whitening is temporary and the whiteness will diminish with time. When people expose their teeth to food and drinks such as coffee or tea, they cause stains which may accelerate the fading of your teeth-whitening results in as little as one month. Those who avoid food and drinks that cause stains may be able to hold out for at least a year before they require another whitening treatment or touch-up.

There are a few steps you can take to help make your whitening last longer. Firstly, avoid eating or drinking anything that can stain your teeth. Some of the foods to avoid include coffee, tea, soda, red wine and berries. If you want to consume them, make sure to thoroughly rinse or brush your teeth after words.

Remember to keep up with tooth brushing twice a day and visit your dentist twice a year to prevent any stains from accumulating!

The best part about doing professional teeth whitening with an experienced dentist in Singapore is the speed and safety. Unlike over-the-counter kits, whitening done by a doctor will usually have a stronger formula that can provide that whiter smile in a single session.

On the other hand, DIY kits will often take at least a week to provide visible results. It is also much safer to get it done with professionals who know exactly what they are doing!
