Teeth whitening is a cosmetic procedure that lightens the colour of teeth and removes stains. A dentist can perform it professionally or at home using over-the-counter products.
Most teeth whitening treatments use peroxide-based bleaching agents. At-home whitening kits usually have 3% to 20% peroxide. This can be hydrogen or carbamide peroxide. In-office treatments have higher levels, ranging from 15% to 43%.
The effectiveness of whitening depends on the concentration of peroxide and the duration of application. Higher concentrations produce faster results, but users should apply them for shorter periods to prevent dehydration and sensitivity.
Both professional and at-home whitening have advantages and limitations. Before using any whitening treatment, consult a dentist. Some individuals may not achieve significant results; whitening products do not affect porcelain crowns or tooth-coloured fillings.
People often use "Whitening" and "Bleaching" interchangeably, but they have different meanings. Teeth whitening is any process that makes teeth appear brighter using bleaching or non-bleaching products.
Bleaching uses peroxide-based agents to remove deep and surface stains, making teeth whiter than their natural colour.
Tooth discolouration occurs when teeth become stained or darkened. It can affect the entire tooth or appear as spots or streaks on the surface. Two main types of discolouration exist:
Professional teeth whitening performed by a dentist delivers faster and more noticeable results than at-home treatments. The bleaching solution used in a clinic is stronger. Dentists may use heat, light, or both to improve whitening.
Most in-office treatments can lighten teeth by three to eight shades. The process usually requires multiple sessions, each lasting 30 to 60 minutes. Some advanced techniques, such as the Zoom system, can achieve results in a two-hour session.
The cost of professional teeth whitening in India varies depending on the clinic and procedure. On average, it ranges from ₹40,000 to ₹80,000 per session.
Several ways to whiten teeth at home exist, varying in effectiveness, cost, and ease of use.
These peroxide-based products are applied directly to the teeth using a brush or thin strip. You typically need to use them once or twice daily for 10 to 14 days, and they can lighten teeth by one or two shades. Results last four months or longer. The cost ranges from ₹800 to ₹4,500.
This method uses a tray that looks like a mouthguard. You fill it with a gel or paste that contains peroxide. Then, you wear it for one to several hours each day for up to four weeks.
You can purchase these kits over the counter or have a custom-fitted tray made by a dentist. The price ranges from ₹12,000 to ₹50,000, depending on whether it is a generic or professional-grade system.
All toothpaste helps remove surface stains because of mild abrasives. However, whitening toothpaste has extra chemicals or polishing agents that improve stain removal. These toothpastes do not contain potent bleaching agents but can brighten teeth by about one shade. Prices typically range from ₹150 to ₹1,000.
These mouthwashes contain hydrogen peroxide and are used for 60 seconds twice a day to help brighten teeth slightly over time. While they are less effective than other whitening methods, they provide a simple way to maintain results.
These gums help prevent stains. People often use them after drinking tea or coffee or using tobacco. While they do not significantly whiten teeth, they help reduce new discolouration.
Maintaining good oral hygiene is the first and most effective step toward whiter teeth. Brushing your teeth twice a day with fluoride or baking soda toothpaste is important. Flossing once a day also helps. Drinking fluoridated water can keep your teeth clean and healthy.
In addition to proper oral care, some natural methods may contribute to a brighter smile.
Certain foods can help protect and strengthen teeth while naturally reducing stains:
Baking soda has mild abrasive properties that help remove surface stains from teeth. A common ingredient in many whitening toothpastes is present. To use it at home, apply a small amount of baking soda to a wet toothbrush and gently brush your teeth. Limit use a few times weekly, as excessive brushing with baking soda can wear down enamel.
Many brands market activated charcoal as a natural whitening agent, and many toothpastes and polishes contain it. However, scientific evidence does not support its effectiveness in whitening teeth. The American Dental Association (ADA) warns that charcoal can be rough on teeth. This may cause enamel damage and make teeth look more yellow over time.
Oil pulling is an old Indian practice. It involves swishing sesame or coconut oil in your mouth for 15 to 20 minutes each day. While some believe it can whiten teeth and improve oral health, little scientific evidence supports these claims.
Several teeth whitening options are available, and the best choice depends on your oral health, desired results, and budget. Consulting a dentist is the safest way to determine which method is most effective for you.
In-office whitening is a highly effective and long-lasting treatment performed by professionals. However, it costs more than at-home methods and dental insurance often does not cover it. Before proceeding, ask your dentist for a cost estimate.
Several factors influence the best whitening method for you:
Regardless of the whitening method you choose, maintaining results requires proper oral care:
Teeth whitening can effectively brighten your smile, but it may cause temporary sensitivity or gum irritation, especially for individuals with pre-existing tooth sensitivity. Improper use of at-home whitening kits can lead to gum burns or even temporary bleaching of the gums.
Whitening treatments work best for yellow-stained teeth but are less effective for brown discolouration. Teeth that appear grey or purple may not respond to bleaching at all. To determine whether whitening is suitable for you, consult a dentist before using over-the-counter products.
Teeth whitening is generally safe when done correctly, but overuse or improper application may pose risks. The potential side effects of excessive or aggressive whitening include:
Emerging research suggests that frequent or prolonged whitening may also lead to:
To ensure safe whitening, follow these guidelines:
Yes, overuse or improper application of whitening treatments can harm your teeth. The process may cause dehydration and mineral loss, particularly calcium, which is essential for strong enamel. Always use whitening treatments in moderation and under professional guidance to prevent long-term damage.
Teeth whitening is an effective way to lighten tooth colour and remove stains using ingredients like hydrogen peroxide. Various safe methods exist, including professional treatments at a dental clinic and at-home whitening products. No matter what method you choose, it is important to talk to a dentist. Also, follow the product's instructions for safety and effectiveness.
Yes, teeth can become yellow because of aging, dietary habits, and poor oral hygiene. Professional teeth whitening treatments, dental bonding, or crowns can restore a brighter appearance. Your dentist can recommend the best option based on the condition of your teeth.
Dental experts recommend an in-office whitening treatment for lasting results. They also suggest using at-home whitening products each month to maintain those results. However, the best method varies for each individual, so it's essential to consult a dentist for personalized advice.
