Everyone loves a bright, white smile, and teeth whitening has become one of the most popular cosmetic dental treatments today. But how does it actually work? Is it safe? And what can you expect from the process? Let’s break down the science behind teeth whitening in simple terms and explain how it can help give you that confident, dazzling smile.
Reasons Why Teeth Become Yellow
Before we see, how teeth whitening works, it’s important to know why teeth get stained or discoloured in the first place. Here are a few common reasons:
- Dark-coloured drinks like coffee, tea, red wine, and cola can stain your teeth over time.
- Smoking or chewing tobacco leaves yellow or brown stains on the teeth.
- As we age, the enamel on our teeth gets thinner, revealing the natural yellow color of the dentin underneath.
- Certain medications, like antibiotics, can cause tooth discoloration.
- Not brushing and flossing regularly can allow plaque and stains to build up on your teeth.
Now, let’s see how teeth whitening can reverse these effects and brighten your smile.
Procedure of Teeth Whitening
Teeth whitening works by using special products that break down stains on the enamel (the outer layer of your teeth) and remove discolouration. Here’s a simple explanation of the science behind it:
- Active Ingredients
Teeth whitening products usually contain hydrogen peroxide or carbamide peroxide as the active ingredient. These are bleaching agents that help break up stains into smaller pieces.
- Oxidation Process
When applied to the teeth, these bleaching agents release oxygen molecules. These molecules penetrate the enamel and dentin layers of your teeth and break the bonds of the stain molecules, making them less visible and ultimately lightening the colour of your teeth.
- Multiple Treatments
Teeth whitening isn’t a one-time process for most people. Depending on the level of staining, you may need multiple treatments to reach the shade of white you want.
Is Teeth Whitening Safe? Myth or Fact.
Teeth whitening is safe when done correctly, despite common myths. Some people believe it harms your teeth, but the fact is, as long as you follow your dentist’s instructions or product guidelines, it’s perfectly safe. Overusing whitening products might cause temporary tooth sensitivity, like discomfort with hot or cold foods, but this usually goes away quickly.
There’s also a myth that whitening products damage your gums, but irritation only occurs if applied incorrectly. When used carefully, there’s little to no risk. Lastly, while some think they don’t need a dentist for whitening, it’s always wise to consult with one to ensure it’s the right choice for you.
Tips for Keeping Your Teeth White
After whitening, you’ll want to maintain your bright smile for as long as possible. Here are a few simple tips,
- Avoid staining foods and drinks like coffee, tea, and red wine, or drink through a straw to limit contact with your teeth.
- Quit smoking, tobacco stains teeth quickly, so quitting will help keep your smile white.
