A bright, white smile can make a world of difference in one's expression and confidence. Tooth discoloration can therefore, be a frustrating impediment to achieving the brilliant smile you deserve. Worse yet, some stains are absorbed deep below the surface, making them seemingly impossible to remove. Fortunately, there are numerous treatment options available to expunge or conceal discoloration, helping patients restore the natural color of their teeth.

What causes stained teeth?

Many dentists believe that it can occur to people within the age groups of 2 to 49. There are many causes that can be associated with discoloration of teeth such as consuming acidic food items as they tend to leave stains on the teeth.

Age is also one of the most important factors that contribute to discoloration of teeth. Other than that beverages such as coffee and alcohol also take away the whiteness of teeth leaving them yellow and stained. There are many remedies for stained teeth both medical and natural. One can conveniently choose accordingly but also consult their dentist before going ahead with their decision.

Types of Tooth Discoloration
Before deciding on a procedure, it's important to understand the type of discoloration present on your teeth. Some stains are more easily removable than others, and as such, may require alternative forms of treatment.

1. Extrinsic Stains: Also called surface stains, these are the most common source of discoloration. Extrinsic stains tend to result in the general darkening or yellowing of teeth, especially along the edges and near the gums. These are typically caused by food, drink, and tobacco use.
2. Intrinsic Stains: Also called deep stains, these tend to be smaller yet more noticeable. As opposed to widespread discoloration, intrinsic stains are localized and a distinctly separate color from surrounding tooth tissue. These are most often caused by medication, overexposure to fluoride, trauma, disease, or enamel erosion.

Whereas surface stains exist within or above the enamel, deep stains are embedded within the inner dentin tissue. Consequently, surface stains are more easily removable. 

Treating Surface Stains
Because surface stains can be removed, they are primarily treated through a simple teeth whitening procedure. Teeth whitening is both safe and long-lasting, allowing patients to restore the color of their smile without any dental restorations.

Treating Deep Stains
Patients looking to restore balance to a smile should consider concealing such stains via restorations. The two most common methods of masking discoloration are dental bonding and porcelain veneers:

1. Dental Bonding: A bonding procedure includes the use of composite resin, which is applied over the surface of a tooth. The tooth is first coated with a layer of tooth-colored resin before the resin is hardened with an ultraviolet light, with additional layers added as needed. The resin thus conceals any discoloration beneath it, while blending in with adjacent enamel.
2. Porcelain Veneers: Veneers are used as a replacement for the surface of a tooth, enhancing it in both color and form. It is an excellent way to alter its overall outward appearance. 

Well, your choice of treatment should be the result of an in-depth discussion with your dentist.
