A host of teeth whitening products are available over the counter and their use can provide white and shinning teeth. When the strips are placed on the teeth, the active ingredient within the formula gradually breaks down. The ingredients of the formula react with oxygen and enter the enamel (outer layer of the tooth).
While all available brands used for whitening the teeth contain peroxide, there is a difference in the concentration of peroxide. While most brands contain formulas in the range of 10 to 20 percent concentration, professional whitening treatments can have a higher concentration of 35 percent, making them more effective.
What Causes White Spots On Teeth After Whitening?
The teeth whitening formula is an acidic medium. Depending upon the condition of the tooth enamel, this formula can cause significant variations in the result. White spots on the teeth after whitening are one of the most common side-effect. While experts suggest that this is not harmful, it is often attributed to loss of water from the tooth enamel during the chemical reaction.
As per experts, white spots are the result of decalcification, which is observed during the early stage of tooth decay. During the initial phase of tooth decay, some areas on the enamel are softer than other areas. While these areas are not apparent prior to the whitening process, they become obvious after the application of the whitening formula. However experts suggest that the whitening process doesn’t aggravate the condition, it just makes it more obvious.
How To Get Rid Of White Spots On Teeth?
Experts are of the opinion that white spots on the teeth is not the result of the whitening process but only become more noticeable after the whitening process. While some suggest that re-hydration of the teeth can deal with about 50% of such white spots, not all hypo-calcified spots disappear naturally.
Experts have recommended a new process of re-mineralization of the enamel. The treatment focuses on using amorphous calcium phosphate on the teeth for a period of two weeks. One should note that this treatment regimen needs to be performed by a qualified dentist and cannot be performed at home. However here are some tips that can help hasten the process and help you get rid of white spots,
- Ensure an utmost oral hygiene. Brush your teeth twice a day and floss at-least once a week.
- Increase the intake of calcium rich foods like low fat milk, cheese, green vegetables, etc. Adequate supply of calcium is important for re-mineralization of the tooth. Magnesium plays a vital role in absorption of calcium and it should be consumed in recommended amount.
- Limit the intake of aerated beverages and coffee.
- Homeopathic drug Kreostote is considered valuable in the treatment of spots and caries in tooth. This medicine should be consumed about three to four times in a day in relatively low potency.
Avoid using over the counter products or chemicals to bleach the teeth. Local application of freshly squeezed lemon juice is natural bleach and can be beneficial in whitening of the teeth. Avoid smoking and caffeine as these are prone to cause demineralization and increase the risk of white spots.
