Teeth Whitening - Love the Dentist (2024)

Love

Tooth whitening, also known as teeth bleaching, is a cosmetic dental procedure aimed at lightening the colour of natural teeth and enhancing their appearance. It is a popular treatment for individuals who wish to achieve a brighter, whiter smile.

Tooth discoloration can occur due to various factors, including ageing, consumption of certain foods and beverages (such as coffee, tea, and red wine), tobacco use, poor oral hygiene, and certain medications. Tooth whitening treatments help to remove stains and restore a more youthful, vibrant appearance to the teeth.

What happens during the tooth whitening process?

Before undergoing any tooth whitening treatment, a consultation appointment is booked to determine the suitability of the procedure for your specific situation. Your dentist will evaluate the condition of your teeth, discuss any potential risks or side effects, and provide guidance on the most appropriate tooth whitening method for you.

It’s important to note that tooth whitening treatments are most effective on natural teeth and may not have the same results on dental restorations, such as fillings, crowns, or veneers. In some cases, additional dental procedures may be necessary to match the shade of the whitened teeth with existing restorations. This is the reason a consultation appointment is paramount prior to any treatment.

There are two primary methods of tooth whitening:

At-home whitening: This method involves the use of custom-fitted trays provided by us from a digital scan taken of the teeth at the consultation appointment. The patient fills the trays with a lower concentration of bleaching gel and wears them over the teeth for a prescribed period, usually a few hours a day or overnight, for a designated period of time (e.g., a few days to a few weeks). At-home whitening takes longer to achieve desired results compared to in-office treatment but offers the convenience of performing the procedure at home.

In-chair professional whitening: This procedure is performed by us within the practice. It involves the application of a higher concentration of bleaching agents, such as hydrogen peroxide or carbamide peroxide, directly to the teeth. The bleaching agent is typically activated by a specialized light. In-chair whitening produces quick and noticeable results, with several shades of improvement achieved in just one 60 minute visit. The results can be topped up with some home whitening over a couple days post treatment, using custom trays and top up gels provided by us.

• Avoid staining substances: For the first 24-48 hours after teeth whitening, it's best to avoid or minimize consumption of staining substances that can undermine the whitening effects. This includes foods and beverages like coffee, tea, red wine, berries, tomato sauce, soy sauce, and tobacco products.
• Be mindful of your diet: Even beyond the initial 48 hours, it's beneficial to be conscious of your diet to prevent staining. Limit your intake of staining substances or rinse your mouth with water after consuming them to minimize contact with your newly whitened teeth.
• Maintain good oral hygiene: Continue to practice excellent oral hygiene habits to keep your teeth clean and healthy. Brush your teeth at least twice a day with a medium soft-bristle toothbrush and fluoride toothpaste. Floss daily to remove plaque and debris from between your teeth. Additionally, consider using a whitening toothpaste to help maintain the whiteness of your teeth.
• Rinse after consuming acidic foods or drinks: Acidic substances can weaken the enamel temporarily, making your teeth more susceptible to staining. After consuming acidic foods or beverages, rinse your mouth with water to help neutralize the acid and minimize its impact on your teeth.
• Use a straw: When drinking beverages that may cause staining, such as coffee, tea, or fruit juices, use a straw to direct the liquid past your front teeth. This can help reduce direct contact between the staining substances and your teeth.
• Avoid tobacco use: Tobacco, whether smoked or chewed, is a major contributor to teeth staining and discoloration. Quitting tobacco use can help maintain the whiteness of your teeth and improve your overall oral health.
• Attend regular dental check-ups: Continue to schedule and attend regular dental check-ups and cleanings. Your dentist can monitor the condition of your teeth, provide professional cleanings, and offer guidance on maintaining your whitened smile.
• Touch-up treatments, if necessary: Over time, the whiteness of your teeth may fade. We can provide top up gels, to use with your custom-fitted trays, to maintain the desired level of whiteness.
