A bright, confident smile can leave a lasting impression. If you feel self-conscious about
stained or discoloured teeth, you are not alone. In Singapore and across Asia-Pacific,
94 per cent of people wish they could smile more freely.
Discolouration, whether caused by daily habits or natural ageing, can make it harder to smile or
speak comfortably in social and professional settings. Luckily, there are effective
options available to help restore the natural whiteness of your teeth and, in turn, your
confidence.
At True Dental Studio, we provide professional teeth whitening services, whether you prefer an
in-clinic treatment ($1,308) or the convenience of a home whitening kit

What Stains Teeth?
Teeth can become stained for various reasons, and it’s not always due to poor oral hygiene. Common causes include:
- Food and Drink: Certain foods and beverages, such as coffee, tea, red wine, and dark berries, contain chromogens which are pigmented compounds that cling to enamel and cause stains. Additionally, some of these items contain tannins and/or are acidic, which can erode enamel and increase the likelihood of discoloration and staining.
- Tobacco Use: Smoking or chewing tobacco introduces tar and nicotine, which lead to stubborn yellow or brown stains.
- Ageing: As enamel wears down with age, the yellowish dentin beneath becomes more visible, giving teeth a duller appearance.
- Poor Oral Hygiene: Infrequent brushing and flossing allow plaque and tartar to accumulate, causing discolouration.
- Medications: Certain antibiotics like tetracycline can cause intrinsic stains during tooth development, and other medications like antihistamines can also affect tooth colour.

Types of Teeth Stain
Teeth stains can be classified into two main categories: extrinsic and intrinsic.
- Extrinsic Stains: These form on the tooth surface and are usually caused by external factors like food, drink, or smoking. They are often easier to treat with regular cleaning or over-the-counter whitening products.
- Intrinsic Stains: These occur within the tooth, typically due to ageing, medication use, or trauma. Intrinsic stains are harder to remove and often require professional whitening.
- Age-Related Stains: A combination of extrinsic and intrinsic factors, where enamel wears down over time, revealing the yellowish dentin beneath, making teeth look duller.
Why Go for Professional Teeth Whitening?
You may be curious about the benefits of professional teeth whitening performed by a dentist, especially when there are many over-the-counter (OTC) options such as whitening toothpaste or mouthwash available. Here are some important reasons to consider choosing professional treatment:

A Brighter Smile
Professional teeth whitening treatments are customised to meet your specific needs, often delivering more significant and noticeable results. These treatments are more effective at targeting deep-seated intrinsic stains compared to OTC products, helping you achieve a whiter and brighter smile that enhances your overall appearance.
Professional & Monitored Process
When you choose professional whitening with custom trays or in-clinic treatment, the procedure is conducted under the supervision of trained dental professionals and is generally considered safe. They will guide you through the process, provide personalised advice, and address any questions or concerns you may have.
Quick, Visible Results
Professional in-office whitening can provide noticeable results after just one session. Depending on the severity of your stains, you may achieve several shades lighter in a single visit, allowing you to enjoy a more radiant smile in a relatively short amount of time.
Long-Lasting Results
While OTC products may provide only temporary improvements, professional whitening treatments can offer longer-lasting results. With proper care and maintenance, your brighter smile may last for several months or even years.
