This is a widely used active ingredient in dental teeth whitening in the UK. It works by breaking down the chemical bonds of stains on the tooth surface and within the enamel. Dentists often use higher concentrations of hydrogen peroxide (up to 35%) for in-office treatments. These stronger formulations can deliver faster and more significant results. For example, a single in-office session using a 35% hydrogen peroxide gel might be able to lighten teeth by several shades in just one hour.
Carbamide Peroxide
Another popular choice. When carbamide peroxide comes into contact with saliva, it breaks down to release hydrogen peroxide. Dentists may use carbamide peroxide in custom-fitted whitening trays for take-home treatments. The concentrations can vary, typically ranging from 10% to 22%. A 16% carbamide peroxide gel in a take-home tray, when used as directed over a couple of weeks, can gradually whiten teeth.
In-Office Whitening Procedures
Zoom! Whitening
This is a well-known system used by many dentists in the UK. It involves applying a high-concentration hydrogen peroxide gel to the teeth. Then, a special LED or halogen light is used to activate the gel. The light helps speed up the whitening process. The treatment usually consists of multiple 15-minute sessions. In total, the in-office procedure can last around 60 to 90 minutes. Patients can expect to see an improvement of 4 to 8 shades on the dental shade guide. However, some may experience temporary tooth sensitivity after the treatment, which usually subsides within a day or two.
Philips Zoom WhiteSpeed
It’s an advanced version of in-office whitening. The gel used in this system has a special formulation that allows for faster penetration and more efficient whitening. The treatment time is often shorter compared to some other in-office methods. With WhiteSpeed, dentists can complete the treatment in about 45 minutes, with similar shade improvement results as traditional Zoom! Whitening.
Take-Home Whitening Options
Custom-Fitted Trays
Dentists take impressions of he pattient’s teeth to create trays that fit precisely. These trays are then filled with a whitening gel, usually carbamide peroxide. The advantage of custom trays is that they ensure the gel is evenly distributed over the teeth, maximizing the whitening effect. Patients are given instructions on how often to wear the trays. It could be for a few hours each day or overnight. Wearing the trays overnight with a 10% carbamide peroxide gel for two weeks is a common regimen. This allows the gel to work gradually while the patient sleeps.
Combination Kits
Some dentists offer combination kits that include both in-office and take-home components. For example, the patient may start with an in-office whitening session to get a quick initial result. Then, they are provided with custom trays and a lower concentration gel for at-home maintenance. This approach helps maintain the brightness achieved in the dental office over a longer period.
PatientAssessment and Suitability
Oral Health Check
Before any teeth whitening treatment, dentists in the UK perform a thorough oral health check. They look for signs of tooth decay, gum disease, or existing dental restorations. If there are cavities, these need to be treated first as the whitening gel can cause discomfort in decayed areas. Similarly, if a patient has gum recession, the dentist will consider whether the treatment could cause sensitivity in the exposed root surfaces.
Medical History Review
Dentists also review the patient’s medical history. Certain medications or medical conditions can affect tooth enamel or the body’s response to the whitening agents. For example, patients with a history of tetracycline use may have permanent tooth discoloration that requires a different approach to whitening.
Post-Treatment Care
Dietary Advice
After teeth whitening, dentists advise patients to avoid staining substances for a period. This includes coffee, tea, red wine, and dark-colored berries. For the first 24 to 48 hours after in-office treatment, it’s especially crucial to stick to a white or light-colored diet. This helps prevent new stains from forming right away and allows the teeth to fully absorb the benefits of the whitening.
Oral Hygiene
Good oral hygiene is emphasized. Patients are reminded to brush their teeth gently twice a day and floss daily. Using a soft-bristled toothbrush helps protect the newly whitened enamel. Some dentists may also recommend using a desensitizing toothpaste if the patient experienced sensitivity during or after the treatment.
Regulations and Safety
UK Regulations
In the UK, teeth whitening is a regulated dental procedure. Only registered dentists, dental therapists, dental hygienists, or dental nurses working under the prescription of a dentist can legally carry out teeth whitening using products containing hydrogen peroxide or carbamide peroxide. This ensures that the treatment is carried out safely and in accordance with proper standards.
Safety Precautions
Dentists follow strict safety protocols. They protect the patient’s gums and soft tissues during in-office treatments using a gingival barrier. This barrier prevents the whitening gel from coming into contact with the gums, reducing the risk of irritation. Additionally, they monitor the patient’s response during and after the treatment to address any issues promptly.
Alternative Treatments and Considerations
Dental Veneers
In some cases where teeth have severe discoloration that cannot be effectively treated with whitening agents, dentists may discuss the option of dental veneers. Veneers are thin shells that are bonded to the front surface of the teeth. They can completely change the color and appearance of the teeth. However, veneers are more invasive and expensive compared to teeth whitening.
Cosmetic Bonding
Another alternative for minor discoloration or chips. Cosmetic bonding involves applying a tooth-colored resin material to the teeth and shaping it to improve the appearance. While it’s not a whitening treatment per se, it can enhance the overall look of the smile in cases where whitening is not the best solution.
Conclusion
In summary, dentists in the UK have a range of teeth whitening options at their disposal. From in-office treatments with high-concentration gels and light activation to take-home custom tray systems, they can tailor the treatment to each patient’s needs. Through proper patient assessment, following safety regulations, and providing post-treatment care advice, dentists ensure that patients can achieve a brighter smile in a safe and effective manner. However, it’s important for patients to understand the limitations of each treatment and to have realistic expectations about the results they can achieve. If you have any concerns or questions about teeth whitening, it’s always best to consult a registered dentist in the UK.
