Frequently Asked Questions About Teeth Whitening

Teeth are not only vital for chewing and speaking but also adding extra charm to your smile. If they are yellow or stained, they do not paint a pretty sight and make you feel embarrassed.

Therefore, several people opt for teeth whitening treatments to make their smiles brighter and more attractive. However, there are several questions related to the dental procedure that baffle the minds of people who want to undergo teeth whitening.

To help you in this regard, we have compiled a set of FAQs that have been answered by renowned and experienced dentists in Hope Island to give you all the required details. Here is everything that you need to know about teeth whitening.

What is Teeth Whitening?

Teeth whitening is a simple procedure that lightens the colour of teeth to make them brighter. It involves using hydrogen peroxide or carbamide peroxide to get rid of the yellowness and stains.

The dentist makes sure to protect the gums with a gel or rubber shield while applying the bleach. The treatment can be completed in one appointment, and you can walk home with a stunning smile.

Which Whitening Options Are Available?

You can opt for at-home bleaching kits, which come with a tray that is filled with the bleaching gel and placed on the teeth. However, you can end up harming your gums while doing this on your own.

The bleaching done by the dentist is more effective in making teeth brighter and keeping the gums unaffected. There are several other products like whitening toothpaste and strips available over the counter, but these are not helpful in lightening.

Is the Teeth Whitening Treatment Permanent?

The whitening procedures are temporary and last for a few months or up to a year depending on your food and drink choices. If you consume too much red wine, coffee, cola, soy sauce, beetroot, berries, etc., you can have your stained teeth back in a couple of months. Thus, to make the results last longer, you have to ensure a healthy diet and proper oral health routine.

Does Teeth Whitening Work on Veneers and Dentures?

No, they do not lighten the colour of dental restorations, which include fillings, veneers, crowns, bridges, and dentures. The bleach is applied only to the natural teeth.

However, it does not cause any damage to the restorations. The only downside is that the colour of the whitened teeth will not match with the prosthetic caps. Thus, you will have to replace them.

Do the Whiteners Affect Teeth Health?

Teeth whitening does not cause any side effects or harm the tooth enamel. The only impact of bleaching is tooth sensitivity immediately after the procedure, and it subsides within 1-2 days. You can use fluoride-based toothpaste to reduce the sensitivity and use a soft-bristled brush gently while cleaning them.

When Should I Avoid Teeth Whitening?

If you have any pre-existing dental conditions, such as cavities or exposed roots, you should not opt for bleaching treatment. Your dentist will suggest getting the cavity treated before going ahead with whitening.

People who have gum diseases are also not the right candidate for the procedure. The bleach can lead to sensitivity of the gums and will not work on exposed roots. So, make sure that you have a healthy mouth before trying the home kits for teeth whitening.

Are the Home Kits Effective?

The over-the-counter teeth whitening kits contain 3% to 20% hydrogen peroxide or carbamide peroxide, while the in-office bleaching agents used by dentists contain 15% to 43% peroxides.

Therefore, the at-home kits are not as effective as the ones administered by the dentist. Also, if the gel has a high concentration of the bleaching agents, it should be kept on the teeth for a shorter duration as it can cause sensitivity.

It can also impact the gums if the tray is ill-fitted or the gel is applied incorrectly. In addition, regular use of these products can affect oral health. Thus, book an appointment with your practitioner rather than taking up the job yourself.

Do the Teeth Whitening Toothpastes Work?

The toothpaste being promoted as whitening products are not effective in making your teeth brighter. They are suitable for cleaning but cannot remove staining and yellowing.

They are safe for prolonged use and helpful in cleaning the surface of the tooth. For the best results, you must ask your dentist for bleaching procedures.

Does Teeth Whitening Remove Plaque?

No, teeth whitening only removes the stains from the surface of the teeth to make them a few shades lighter. On the other hand, the removal of plaque and tartar need teeth cleaning, which is done by the dentist with the help of scaling and polishing.

These deposits are hardened over time and cannot be removed by bleaching. Teeth cleaning is highly recommended if you notice plaque and tartar as it can cause tooth decay and gum disease.


If the peroxide in the whitening agent penetrates the soft layer of dentin, it can cause sensitivity. Thus, it is ideal to consult your dentist in Hope Island for teeth whitening rather than opting for DIY products.
