Different reasons can cause the colour of teeth to deteriorate — in other words, discolouration can occur. The causes of discolouration may include ageing; wear due to acid or trauma; discolouration caused by drugs, foods, or incorrect brushing habits; bad habits such as smoking; diseases; and substances such as fluoride. Many of these can be removed by bleaching (whitening), and the cause of the discolouration plays an important role in how effective the bleaching process will be. Different methods are used in teeth whitening, which divide into two types depending on whether the teeth are vital or non-vital: intracoronal and extracoronal whitening. Our tips for maintaining a bright smile include regular dental check-ups and good oral hygiene. Staying hydrated and limiting sugary snacks can also help prevent further discolouration, and a good-quality toothpaste — with whitening strips used as directed — can enhance your smile’s radiance.
Over-the-Counter Whitening Products
One of the most accessible ways to begin your teeth whitening journey is with over-the-counter (OTC) whitening products. These 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 a recognised quality mark, such as the American Dental Association (ADA) Seal of Acceptance, which indicates that a product is both safe and effective. 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 treatment, or in-office procedures that can lighten your teeth several shades in a single visit. You can check our dental treatment prices for details.
Benefits of Professional Whitening
Professional treatments are closely monitored, which reduces the risk of gum irritation and protects the health of your teeth. The results also 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 discolouration.
Oral Hygiene
Maintaining good oral hygiene is crucial. Brushing twice a day, flossing regularly, and using an antiseptic mouthwash help keep your teeth clean and reduce the build-up of plaque, which can cause discolouration.
Diet Choices
What you eat and drink greatly affects the colour of your teeth. Limiting stain-causing beverages like coffee, tea, and red wine, and eating 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 may 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 your dentist before trying anything new, to make sure it’s safe and won’t harm your enamel. By exploring these tips, you can work towards reducing tooth discolouration and achieving a healthier, brighter smile. Remember, while aesthetic improvements are important, nothing beats the confidence that comes with good oral health.
Intracoronal (Internal) Teeth Whitening
This method involves applying a whitening agent inside a non-vital (root-treated) tooth. It is used to lighten a single tooth that has darkened from the inside after the nerve has died or after root canal treatment.
Extracoronal (External) Teeth Whitening
This procedure involves applying a whitening agent to the outside of vital (living) teeth. It can be done in two ways: home bleaching and office bleaching.
Home Whitening
Special moulds are prepared by taking measurements of the patient’s teeth. The patient puts the bleaching agent into these moulds and places them over their teeth. At periodic check-ups, the dentist decides how many hours a day the trays should be worn and for how long to continue — approximately 2 to 8 hours per day is usually enough, and the treatment continues for a week or two.
Office Whitening
This is a faster and more effective type of whitening — a professional method performed by the dentist in the clinic. The dentist first covers the gums with a protective barrier, then applies the whitening material to the teeth. A light or laser is used to activate the whitening agent. A session may take from 45 minutes to 1 hour, and several supportive sessions may be needed until the desired whiteness is achieved.
Bleaching can be applied at almost any age and is harmless when performed correctly. Depending on the person’s smoking, eating, or brushing habits, further top-up treatment may be required in the future. Some sensitivity may occur during the treatment process, which fluoride applications can help relieve. A patient can achieve a result up to around 10 shades lighter, depending on the case. During treatment, the patient should avoid the factors that cause discolouration in the first place.
