Different reasons can cause colour deterioration on the teeth, in other words, discolourations may occur. The causes of discolouration in teeth may be ageing, wearing due to acid or trauma, discolouration due to drugs, foods, incorrect tooth brushing habits, bad habits such as smoking, diseases and substances such as fluorine. Many of these can be removed by bleaching(whitening). The cause of discolouration plays an important role in the effectiveness of the bleaching process. Different methods are used in teeth whitening. It differs into two parts according to the application if live and non-living teeth: Intracoronal and extra coronal whitening.


One of the most accessible ways to begin your teeth whitening journey is with over-the-counter (OTC) whitening products. These products include whitening toothpaste, strips, and gels that contain mild bleaching agents. It's important to follow the instructions carefully to avoid overuse, which can lead to tooth sensitivity.

Choosing the Right Product

When selecting an OTC whitening product, look for the American Dental Association (ADA) Seal of Acceptance. This seal indicates the product is both safe and effective for use. Keep in mind that while these products can improve the appearance of your smile, they may not offer results as dramatic as professional treatments.

Professional Teeth Whitening

For those seeking more significant results, professional teeth whitening performed by a dentist is the way to go. Dentists use stronger bleaching agents and can provide custom-fitted trays for at-home treatments or in-office procedures that can lighten your teeth several shades in a single visit.

Benefits of Professional Whitening

Professional treatments are closely monitored, which reduces the risk of gum irritation and ensures the health of your teeth. Additionally, the results tend to last longer than those achieved with OTC products, especially when you maintain good oral hygiene and limit stain-causing foods and drinks.

Daily Habits for a Brighter Smile

Apart from products and professional treatments, there are daily habits that can help prevent tooth discoloration.

Oral Hygiene

Maintaining good oral hygiene is crucial. Brushing twice a day, flossing regularly, and using an antiseptic mouthwash can help keep your teeth clean and reduce the buildup of plaque, which can cause discoloration.

Diet Choices

What you eat and drink greatly affects the color of your teeth. Limiting the intake of stain-causing beverages like coffee, tea, and red wine, and consuming more teeth-friendly foods like crunchy fruits and vegetables can help maintain a brighter smile.

Home Remedies

For those interested in natural methods, there are several home remedies that can assist with teeth whitening.

Baking Soda and Hydrogen Peroxide

A popular home remedy is a paste made from baking soda and hydrogen peroxide. This mixture can help remove surface stains and whiten teeth over time.

Oil Pulling

Oil pulling with coconut oil is another natural technique believed to remove toxins and improve oral health, potentially leading to whiter teeth.

It's essential to approach home remedies with caution and to consult with your dentist before trying new treatments to ensure they're safe and won't harm your enamel.

By exploring these teeth whitening tips, you can work towards eliminating tooth discolouration and achieving a healthier, brighter smile. Remember, while aesthetic improvements are important, nothing beats the confidence that comes with good oral health.

Intracoronary Teeth Whitening

It is based on the application of a whitening agent through the tooth in inanimate teeth.

Extracorporeal Teeth Whitening

This procedure is about applying a whitening agent from the outside of the living teeth. It can be done in two ways called home and office bleaching.

Home Type Whitening

Special moulds are prepared by measuring the teeth of the patient. The patient puts the bleaching agents into these moulds and places them on his teeth. During the periodic checks, the physician decides how long this procedure will be used during the day and how long it will continue. Approximately 2 to 8 hours per day is enough. The application continues for a week or two.

Office Type Whitening

This is a faster and more effective whitening type. It is a professional whitening method performed by the dentist in the clinic. Dentist covers the gums with preservatives. Subsequently, he applies the materials used to bleach the teeth. By using rays, these whitening drugs are provided to the function. The session may take from 45 minutes to 1 hour. Several supportive sessions may be performed until the desired whiteness is achieved. Bleaching can be applied at almost any age. It is harmless when applied correctly. Depending on the person's smoking, feeding or brushing habits, further reinforcement may be required in the future. Sensitization may occur during the treatment process. Fluorine applications may eliminate these sensitivities. The patient can achieve up to 10 tons of bleaching depending on the case. During treatment, the patient should avoid factors that may cause discolouration.
