Dentists whiten teeth using professional-grade bleaching agents that penetrate the enamel to break down stubborn stains. This process, known as teeth whitening, is designed to restore the natural brightness of teeth, enhancing smiles and boosting confidence.
Tooth whitening is among the most sought-after cosmetic dental procedures. With over 45% of adults expressing dissatisfaction with their teeth’s appearance, it is no wonder that teeth whitening treatments are increasingly popular.
What Does the Tooth Whitening Process Involve?
According to the Oral Health Foundation, nearly 40% of adults in the UK have considered whitening their teeth. This surge in demand reflects the growing importance of dental aesthetics in both personal and professional settings.
While over-the-counter products promise quick fixes, professional tooth whitening performed by a dentist is a carefully controlled process. It typically begins with an assessment of your oral health. This step is crucial, as untreated cavities or gum disease can worsen under bleaching agents.
Once suitability is confirmed, professional bleaching methods will be used. Whilst it is possible to have in-surgery whitening, take-home whitening kits have become increasingly popular.
Usually impressions of your teeth will be taken to craft a custom-fit mouthguard. Under supervision, you will apply the whitening agent using the mouthguard, typically over two to four weeks. This method ensures controlled and gradual lightening of your teeth’s shade.
Are There Different Types of Tooth Whitening Offered by Dentists?
Dentists offer various whitening methods, including:
- In-Surgery Whitening: This is the quickest method, carried out in a dental practice. It involves applying high-strength peroxide gel, often activated by a light source, producing immediate results.
- Take-Home Whitening Kits: Custom-made trays fitted to your teeth allow for whitening at home under dental supervision. This method usually takes two to four weeks, with the added advantage of gradual, more natural-looking results.
- Combination Whitening: Some patients opt for an in-surgery session followed by a take-home kit. This approach enhances the initial brightness while enabling long-term maintenance.
Why Consider Tooth Whitening?
Teeth can become discoloured over time due to several factors. Ageing naturally darkens teeth, while dietary choices such as tea, coffee, red wine and certain fruits like blackcurrants can lead to staining.
Smoking is another common cause of tooth discolouration due to tobacco, and some medications, like antibiotics, can cause intrinsic stains beneath the tooth surface. Identifying the specific cause of discolouration is important to determine the most effective tooth whitening approach.
How Long Does the Treatment Take?
The duration of the treatment varies based on individual needs but generally spans two to four weeks. Consistency in applying the whitening product as directed is crucial for optimal results.
To prolong the effects of tooth whitening practice good oral hygiene by brushing your teeth twice daily and flossing regularly. Reduce intake of beverages and foods known to stain teeth.
It is also recommended to avoid smoking as tobacco can quickly reverse whitening effects. Routine dental check-ups will help to maintain oral health and enhance the longevity of the whitening treatment.
Is Tooth Whitening Suitable for Everyone?
While tooth whitening is effective for many, it is not suitable for everyone. Pregnant women, individuals with gum disease, tooth decay or certain types of staining may not be ideal candidates. A thorough dental examination is essential to determine suitability and ensure safety.
Additionally, those with sensitive teeth or existing dental restorations, such as crowns, veneers or fillings, should be aware that whitening treatments may not produce uniform results. Restorations do not lighten like natural teeth, which can lead to uneven coloration. Consulting with your dentist helps ensure you achieve the best outcome tailored to your dental health and aesthetic goals.
Why Is Professional Tooth Whitening More Effective Than Home Kits?
Home kits can produce some improvement, but their peroxide concentrations are significantly lower than those used by dentists. Over-the-counter products often contain 3% to 6% hydrogen peroxide, whereas professional treatments can use up to 40% under safe supervision. This substantial difference means in-clinic whitening delivers more dramatic and longer-lasting results.
Additionally, dentists tailor the procedure to individual needs. They can address uneven discolouration or treat teeth with unique sensitivities. Home kits offer a one-size-fits-all solution, which may lead to patchy whitening or discomfort.
Do Whitening Treatments Damage Teeth?
When performed by a qualified dental professional, tooth whitening is safe. Extensive research has shown that dental bleaching does not weaken tooth enamel when conducted appropriately. A 2019 study published in the British Dental Journal found that professional whitening treatments pose minimal risk when guidelines are followed.
However, overuse of whitening products, especially unsupervised, can lead to enamel erosion and increased sensitivity. This is why seeking dental advice before any whitening treatment is essential.
What Should You Expect After a Whitening Treatment?
It is common to experience mild sensitivity following whitening. This sensation usually subsides within 48 hours. Dentists often recommend desensitising toothpaste or fluoride treatments to alleviate discomfort.
Avoiding staining substances immediately after treatment is advised. Teeth are more susceptible to re-staining during the first 48 hours, often referred to as the ‘white diet’ phase. Consuming pale foods such as chicken, rice and milk can help maintain the new shade.
Are There Any Risks Associated With Tooth Whitening?
While tooth whitening is largely safe, potential side effects include gum irritation as whitening gels can irritate the gums if they come into contact with soft tissues. Increased tooth sensitivity to hot or cold is also a common temporary side effect.
These issues are typically short-lived. Consulting a dentist ensures treatments are carried out safely, reducing the likelihood of adverse reactions.
How Long Do Whitening Results Last?
Tooth whitening is not permanent, but its longevity depends on lifestyle factors and oral hygiene. Professional treatments often maintain results for up to three years, though this varies between individuals.
Smoking, frequent consumption of coffee, tea, red wine or highly pigmented foods can cause stains to reappear sooner. Brushing twice daily, regular dental check-ups and reducing stain-inducing habits help extend the brightness of whitened teeth.
Final Thoughts
The expertise of a dental professional is the cornerstone of successful whitening. Dentists not only enhance tooth colour but also ensure the process aligns with overall oral health. Customised treatment plans consider tooth structure, gum health and individual sensitivity levels.
Ultimately, the difference lies in precision and safety. Professional tooth whitening delivers predictable results, ensuring a brighter, healthier-looking smile without compromising oral health.
