5 things you need to know about teeth whitening

                           

Have you ever felt uncomfortable smiling because your teeth appear more yellow?

Teeth whitening involves bleaching the teeth to achieve the desired shade. Our team at Maida Smiles Clinic will evaluate all different shade options, and together, we can achieve the most natural-looking result for your teeth.

Whitening products typically use hydrogen peroxide or carbamide peroxide. The bleach soaks into the dentine (the main part of the inside of the tooth, which is slightly softer than the enamel) and reacts with the coloured molecules that cause discolouration.

Your teeth are like sponges…they absorb.

Your teeth have pores, just like those on your face. This means the colour of everything you eat or drink will be absorbed into those pores. Coffee, wine, berries, and smoking are all known to stain your teeth actively. Over time, your habits change the natural colour of your teeth, and they become darker. Unfortunately, these stains are unlikely to ever go away without active removal. This is when teeth whitening comes in handy! The gel applied to your teeth works by entering your dentine and gently pushing stains out until you have reached your desired shade of white.

Teeth whitening does not damage your teeth.

Just like aggressive brushing of your teeth, abuse of any kind can damage your oral health. However, if used as instructed, professional teeth whitening is incredibly safe. The whitening process uses active ingredients to temporarily open pores in your teeth and lift stains. Professionally applied treatments typically have 35%-40% of hydrogen peroxide, while over-the-counter products have up to 10%. These types of peroxide compounds have been regularly used in various dental treatments for years. There is strong scientific evidence that the compounds and treatment are safe and that whitening your teeth will not cause any damage. In fact, after each whitening session, your teeth naturally remineralize and rehydrate.

 The difference between in-clinic or at-home whitening.

Many patients ask us whether there are differences between take-home teeth whitening kits and the Zoom in-chair laser treatment. The differences are quite significant, but there are no hard and fast rules for choosing either.

Which procedure you decide to choose all comes down to personal preference, how much you are willing to spend on teeth whitening, and your sensitivity tolerance.

The Zoom professional whitening option is slightly more costly than home-use solutions but provides a more secure whitening method as a dental professional performs it. Results can be more precise and are seen immediately after a single appointment. For those with more sensitive teeth who do not mind a longer process, a professional take-home whitening kit is the way to go! This option is also slightly less expensive. However, keep in mind that it will require discipline and consistency. Ideally, You should use the system for 15 minutes every day before bed. A bonus of the take-home kit is that you can maintain your results for as long as you desire. Refill bleach tubes can be purchased through the practice.

Is the procedure painful?

No, professional teeth whitening will not cause pain. However, tooth sensitivity during treatment is completely normal due to tooth dehydration. Nevertheless, 50% of patients experience little to no sensitivity and can sit through the entire procedure. The other 50% of patients cannot complete the full four rounds due to sensitivity. If you have more sensitive teeth, you can do a few things at home to tackle this before your treatment. For example, using sensitive toothpaste for at least 1 month before the procedure is a great start.

Am I suitable for the procedure?

You most likely are. However, you must have a check-up and clean-up before the procedure. This is because we do not want to place bleaching agents in areas that may have decay. This will make the procedure painful and uncomfortable as decayed areas are porous.

A clean is required to ensure the teeth are free from debris, plaque, and tartar build-up. This is recommended a few days to a week before the procedure. By ensuring the teeth are free from build-up, we can ensure an even bleaching result. Teeth that are bleached without having a scale and clean prior can end in an uneven and patchy result.
