Why Do Teeth Stain?
Tooth discolouration is extremely common and has nothing to do with cleanliness. Understanding the cause helps choose the right treatment.
Tea, coffee, red wine, colas, and curries are the leading causes of extrinsic (surface) staining. These pigments accumulate in the microscopic pores of tooth enamel over time.
As we age, the outer enamel layer thins through normal wear, revealing more of the naturally darker dentine beneath. This is entirely natural and very effectively treated by whitening.
Nicotine and tar from smoking or chewing tobacco penetrate deep into enamel and cause persistent, heavy staining that is difficult to shift with ordinary brushing alone.
Certain antibiotics (particularly tetracycline taken in childhood), antihistamines, and blood pressure medications can cause intrinsic staining — discolouration from inside the tooth. This type responds differently to whitening and is assessed individually.
Professional Whitening — Two Ways
Both options use clinically safe, dentist-grade whitening agents. Your choice depends on how fast you want results and your lifestyle.
Is Professional Teeth Whitening Safe?
Yes — when performed or supervised by a qualified dental professional. Here is what makes clinic-based whitening safe and over-the-counter products risky.
- Clinically approved, dentist-grade whitening agents at the correct concentration
- Gums and soft tissue are protected before treatment begins
- Suitability is checked first — not everyone is a candidate
- Sensitivity is managed with professional desensitising agents
- Results are predictable and consistent
- No risk of enamel damage when performed correctly
- Often too weak to produce meaningful results
- No pre-screening — can damage existing fillings or crowns
- Ill-fitting trays allow gel to leak onto gums, causing irritation
- No professional to manage unexpected sensitivity
- Unregulated products may contain harmful concentrations
- Results are inconsistent and frequently disappointing
Who Is a Good Candidate for Whitening?
Most healthy adults with natural teeth are suitable. A quick assessment at our clinic confirms this.
