How do Teeth get Discoloured?

Teeth discolouration occurs in two forms: intrinsic and extrinsic. Maintaining natural whiteness over time is challenging due to various factors. Intrinsic stains result from aging, trauma, exposure to certain medications, and, in some cases, genetics. These stains are resilient and difficult to eliminate, necessitating professional assistance for optimal results, such as the support provided by Myra Smiles Dental & Implant Centre. 

Extrinsic stains occur on the top surface of the teeth when you continue to consume coloured foods and beverages like coffee, tea, red wine and certain fruits. Also, habits like smoking or inadequate oral hygiene can contribute to this discolouration.  

Science of teeth whitening- Explained

Teeth whitening, also known as teeth bleaching, is a typical process designed to lighten the shade of the teeth and remove stains and discolouration. Though many teeth whitening products are available, it is better to go for professional teeth treatments at our dental clinic 

The most used method of professional teeth whitening uses bleaching agents like hydrogen peroxide or carbamide peroxide, which seeps into your enamel to remove stains and improve the colour of the teeth. 

The teeth whitening procedure involves the following steps: 


Before the teeth whitening procedure, Dr Ravin Patel will thoroughly check your teeth and gums. The next step will start once he confirms they are healthy and robust enough for the procedure. If any gum issues, bleeding, or cavities are discovered, they will be addressed beforehand.

Safety Measures

Gums and soft tissues are the most sensitive parts, which can get damaged because of the bleaching agent applied during the procedure. So, a protective gel is used on your gums and tissues before applying the teeth whitening agent. This will help reduce the irritation during the treatment.


The bleaching agent-containing whitening gel is administered using a customised teeth tray, ensuring even application without smudging.


Once the gel is applied evenly, a special laser activates the bleaching agent, improving its effectiveness. This laser helps speed up the teeth whitening process and get optimal results quickly.


Our chief dentist, Dr Ravin Patel, will supervise the progress and adjust the pattern or intensity of the procedure if needed to ensure the expected level of whitening is achieved without damaging the gums and tissues.

Post-treatment Care

Once the process is completed, you will be given simple instructions on maintaining the whitened teeth and avoiding unnecessary habits and food that can be the reason for teeth discolouration. These simple instructions may include day-to-day activities like brushing, goggling, flossing and routine dental check-ups.
