Most of us desire that sparkling smile which can add to our feeling of empowerment and confidence. So, teeth whitening is necessary to achieve that. It can not only lighten your teeth several shades, but also remove plaque and other problems from your teeth almost instantly!

What is Teeth Whitening?

Tooth whitening is an efficient way of lightening the color of your teeth without losing the important tooth surface enamel. Teeth whitening can not bring about a complete transformation, but it probably can lighten the existing shade to make you look better.

Teeth whitening can be achieved in a number of different ways, and in this guide we will cover all of them! From natural teeth whitening recipes to home teeth whitening kits and professional cosmetic dental procedures you will find the best ways to whiten teeth here.

Is Whitening Safe for My Teeth?

This is a question that troubles everyone who is considering undergoing a tooth whitening treatment. So, here is the answer. In simple terms, whitening is safe, as the chemicals or ingredients used to remove stains do not in most cases affect the structure of teeth.

But, we can not say with 100% certainty that there are no side effects at all because temporary side effects do occur, depending on the type of treatment.

The side effects generally include tooth sensitivity and gum pain. But there’s no need to worry, in the case of professional whitening treatments your dentist or treatment centre will take some precautions to avoid any such temporary issues and minimize the potential for tooth sensitivity.

The bleaching agents used in most teeth-whitening products are hydrogen peroxide (H2O2) and carbamide peroxide based.

Carbamide peroxide is one of several very common base ingredients for home whitening products such as gel trays as it has a long shelf life and stability.

You can use this product for extended periods as it has shown a low risk for sensitivity.

It can also be left on the teeth for longer periods with less risk of sensitivity.

Virtually all professional bleaching methods use hydrogen peroxide which is a faster-acting bleaching agent. Hydrogen Peroxide can lighten your teeth at least five shades in an hour.

So, many people prefer these treatments. But, that is not to say that natural teeth whitening methods are inferior, in fact natural ingredients and methods can have very comparable results, as we will show you later in the article.

Teeth Discoloration

Main Causes of Teeth Discoloration

If you are eager to know the causes of teeth discoloration, here’s the answer. Just as there are some ways to lighten teeth, there are also several different ways that teeth can become discolored.

The leading causes of darkened teeth are genetics, antibiotics, and certain foods, plus teeth tend to darken as we age.

It’s time to get a little scientific but bear with us, this is useful information. There are two types of tooth discoloration:

  1. Extrinsic Tooth Discoloration: Extrinsic staining is caused by direct contact with various foods and other agents. They include tobacco and foods containing tannins such as red wine, coffee, and tea. You can get stains easily from smoking or chewing tobacco. So, avoid it at all costs, not just for your teeth but for your overall health as well. 
  2. Intrinsic Tooth Discoloration: Internal tooth discoloration is caused by changes in the enamel of the tooth and the dentin.The main causes of internal tooth discoloration are exposure to high levels of fluoride, tetracycline, use of antibiotics as a child, developmental disorders, tooth decay, restorations, root canal issues, and trauma. Intrinsic tooth discoloration can happen with aging as enamel loses its youthful translucency, becoming less porous; this makes the underlying dentin more visible as it thickens and becomes more yellow over time. Intrinsic discoloration is also caused by exposure to excessive fluoride or the antibiotic tetracycline during tooth formation, inherited developmental disorders, and jaundice in childhood. For teeth that have erupted already, the leading causes of intrinsic discoloration are tooth decay, restorations, pulp death (root canal problems) and trauma to developing teeth. It’s possible to have both extrinsic and intrinsic discoloration at the same time

Other Causes of Teeth Discoloration

  • Disease: There are few diseases which affect enamel and dentin. They lead to discoloration of the teeth. Some kinds of Infections in pregnant mothers can lead to teeth discoloration in the baby.
  • Medications: Some medicines including Antihistamines, antidepressants, and high blood pressure drugs can lead to teeth discoloration.
  • Age: There is a direct correlation between tooth color and age. Over the years, teeth darken as a result of wear and tear and stain accumulation. Teenagers will likely experience immediate, dramatic results from whitening. In the twenties, as the teeth begin to show a yellow cast, teeth-whitening may require a little more effort. By the forties, the yellow gives way to brown and more maintenance may be called for. By the fifties, the teeth have absorbed a host of stubborn stains which can prove difficult (but not impossible) to remove.
  • Starting color: We are all inborn with a teeth color which ranges from yellow-brownish to greenish-grey and intensifies over time. Yellow to brown is more responsive to the bleaching techniques than the green-grey shades.
  • Translucency and thinness: The changes in teeth color may be due to genetic traits that become more pronounced with increasing age. All the teeth show some kind of transparency, but those which are opaque and thick have an advantage i.e they appear lighter in color, and exhibit more sparkle and are responsive to bleaching. According to the dentists, transparency is the only condition which cannot be corrected by any form of techniques present in teeth whitening.
  • Eating habits: Eating habits also effect your teeth color. The frequent consumption of red wine, coffee, tea, cola, carrots, oranges & other colored beverages causes teeth staining. The acidic foods like citrus fruits and vinegar also contribute to enamel erosion which makes your teeth lose their natural gloss and shine. So, the surface becomes more transparent and results in more of the yellow-colored dentin shows through.
  • Smoking habits: Nicotine and nicotine containing products will leave brownish deposits on teeth  which slowly gets absorbed into the tooth structure and cause intrinsic discoloration.
  • Drugs or chemicals: When pregnant mothers use Tetracycline during tooth formation in the child then it results in dark gray or brown ribbon stains on the newborn which are tough to remove. Excessive consumption of fluoride causes fluorosis and associated areas of white mottling.
  • Grinding: Some people have the habit of grinding their teeth when they are subjected to stress. Most frequently caused by stress, teeth grinding (gnashing, bruxing, etc.) can add to micro-cracking in the teeth and can cause the biting edges to darken.
  • Trauma: Some serious injuries to teeth may cause cracks. If they are not treated properly, then the crevices will collect debris which may lead to staining

Teeth Whitening Methods

There are many teeth whitening methods which you can use. But not all can give you the same results. Let’s explore all the available options to whiten your teeth.

Professional Teeth Whitening

Professional treatments are rendered by a certified physician. They involve the use of highly concentrated whitening gels. They are not readily available over the counter because they are less safe if used at home. The Whitening gels mostly contain hydrogen peroxide or carbamide peroxide. These bleaching agents will break down the stains and remove them. After applying them allow them to settle down for 30 minutes to 1 hour. If you have brown stains, this method works great. But bleaching is not as useful for gray colored teeth which usually require custom bleaching trays. These professional teeth whitening systems are usually of two types –  In Office Whitening Systems and Take Home Whitening Systems.

In Office Whitening Systems

As the name indicates, the whole procedure should be held at your physician’s practice. There, they will apply a gel to your teeth and leave it on for less than an hour. In some processes heat, laser or blue light may be used to increase the bleaching action. The steps included in in-office whitening systems are

  • Applying teeth whitening gels

Laser Teeth Whitening

Then, the laser lights will be focused on teeth to activate the bleaching product. The best part of using this laser light is this product can eradicate nicotine stains. This is the fastest way to whiten your teeth. This dental whitening procedure is repeated over a series of 15-20 minutes until you get a whiter shade. But, this is certainly one of the most costly whitening treatments.

Take Home Whitening

Do not confuse this take home whitening with OTC methods. In this approach, the physician will render the patient with a custom-made mouth tray made of thin, flexible plastic. You should fill this tray with the provided whitening gel and insert this such that the gel touches your teeth. Leave it  for the prescribed period. Take home whitening treatments include:
