Teeth Whitening – A Beginners Guide

Teeth whitening is a cosmetic dental procedure that involves lightening the colour of your teeth. With the growing desire for a brighter and more confident smile, teeth whitening has become one of the most sought-after cosmetic dental treatments. However, many people are not well informed about the process and its outcomes, making it difficult for them to make an informed decision. In this article, we’ll provide a beginner’s guide to teeth whitening, giving you all the information you need to know before you decide to go ahead with the treatment.

Why do teeth get discoloured?

There are several reasons why teeth may become discoloured. Some of the most common causes are:

Aging: As we get older, our teeth naturally start to yellow and become more brittle.
Drinking coffee, tea, or red wine: These beverages contain pigments that can stain our teeth.
Smoking: The tar and nicotine in cigarettes can cause yellow and brown stains on the teeth.
Poor oral hygiene: Neglecting your teeth and gums can lead to a buildup of plaque, which can cause tooth discolouration.

Types of teeth whitening treatments

There are two main types of teeth whitening treatments: in-office whitening and at-home whitening.

In-office whitening is performed by a dental professional and is the quickest way to get a brighter smile. The dentist will apply a concentrated hydrogen peroxide gel to your teeth, which will be activated by a special light. This process can take anywhere from 30 minutes to an hour, and you can expect to see immediate results. However, this type of treatment can be more expensive than at-home whitening.

At-home whitening involves using a kit that you can use in the comfort of your own home. These kits usually include a custom-fitted tray and a gel that you will apply to your teeth for a set amount of time each day. This type of treatment is usually more affordable, but results take longer to see and may not be as dramatic as in-office whitening.

What to expect from teeth whitening

Teeth whitening is a safe and effective way to improve the appearance of your smile. However, it is important to note that not all teeth will respond equally to the treatment. Some teeth may become lighter than others, and some teeth may not change colour at all. The results of teeth whitening are also not permanent and will need to be touched up every few months to maintain your desired level of whiteness.

It is also important to note that teeth whitening can cause sensitivity in some people. This sensitivity is usually temporary and should go away within a few days of the treatment. If you experience discomfort, you should speak to your dentist to discuss alternative options.

How to prepare for teeth whitening

Before you decide to go ahead with teeth whitening, it is important to schedule a consultation with a dental professional. Your dentist will examine your teeth to make sure that they are healthy enough for the treatment, and to determine if you have any underlying dental issues that could affect the outcome.

It is also important to have good oral hygiene habits in place before you start the treatment. This means brushing and flossing regularly, and using mouthwash to keep your mouth clean. If you have any existing dental problems, such as cavities or gum disease, it is important to have these treated before you start the whitening process.
