How to Avoid Sensitivity During Teeth Whitening
Teeth whitening is a popular cosmetic procedure that can significantly enhance your smile. However, a common side effect is teeth sensitivity, which can range from mild discomfort to sharp pain. Fortunately, there are several strategies you can employ to minimise or even eliminate this sensitivity, ensuring a more comfortable and enjoyable whitening experience. This article provides practical tips and advice to help you navigate teeth whitening with minimal discomfort.
Why Does Teeth Whitening Cause Sensitivity?
Before diving into solutions, it's helpful to understand why sensitivity occurs. Whitening agents, typically hydrogen peroxide or carbamide peroxide, penetrate the enamel and dentin layers of your teeth to break down stain molecules. This process can temporarily dehydrate the teeth and open up the dentinal tubules, which are microscopic channels that lead to the nerve of the tooth. When these tubules are exposed, hot, cold, sweet, or acidic stimuli can easily reach the nerve, causing sensitivity.
Using Desensitising Toothpaste Before and After Treatment
One of the most effective ways to combat teeth sensitivity is by using desensitising toothpaste. These toothpastes contain ingredients like potassium nitrate or stannous fluoride, which help to block the dentinal tubules and reduce nerve sensitivity.
How Desensitising Toothpaste Works
Potassium Nitrate: This ingredient works by depolarising the nerve, making it less responsive to stimuli. It essentially calms the nerve down, reducing the sensation of pain.
Stannous Fluoride: This form of fluoride helps to strengthen enamel and block the dentinal tubules, preventing irritants from reaching the nerve.
Best Practices for Using Desensitising Toothpaste
Start Early: Begin using desensitising toothpaste at least two weeks before your whitening treatment. This allows the active ingredients to build up and provide maximum protection.
Use Regularly: Continue using the toothpaste twice daily, even after your whitening treatment is complete. This helps to maintain the desensitising effect.
Apply Directly: For extra relief, you can apply a small amount of desensitising toothpaste directly to sensitive areas and leave it on for a few minutes before rinsing. This allows for more concentrated contact with the affected areas.
Common Mistakes to Avoid
Not starting early enough: Waiting until you experience sensitivity to start using desensitising toothpaste is often too late. Prevention is key.
Using it inconsistently: Missing doses can reduce the effectiveness of the toothpaste.
Rinsing immediately after brushing: Allow the toothpaste to sit on your teeth for a minute or two before rinsing to maximise its impact.
Adjusting Treatment Duration and Frequency
The intensity and duration of your whitening treatments can significantly impact sensitivity. Overdoing it can exacerbate the issue, while adjusting the treatment can make it more manageable.
Shorter Treatment Times
Reduce Exposure: If you're using at-home whitening kits, try shortening the duration of each treatment session. For example, if the instructions recommend 30 minutes, start with 15 or 20 minutes and see how your teeth react.
Less Frequent Treatments
Space Out Sessions: Instead of whitening every day, try whitening every other day or every few days. This gives your teeth time to recover and remineralise between treatments.
The Importance of Gradual Whitening
Build Tolerance: A gradual approach to whitening allows your teeth to slowly adjust to the process, reducing the likelihood of sensitivity. This is often more effective than trying to achieve dramatic results quickly.
When to Seek Professional Advice
Persistent Sensitivity: If you experience significant sensitivity even with adjusted treatment times and frequencies, consult with a dental professional. They can assess your teeth and recommend alternative whitening methods or treatments.
Choosing a Lower Concentration Whitening Gel
The concentration of the whitening gel plays a crucial role in the degree of sensitivity you experience. Higher concentrations are more effective at whitening, but they also carry a higher risk of causing discomfort.
Understanding Whitening Gel Concentrations
Hydrogen Peroxide vs. Carbamide Peroxide: Whitening gels typically contain either hydrogen peroxide or carbamide peroxide. Carbamide peroxide breaks down into hydrogen peroxide, so the effective concentration is lower. For example, a 10% carbamide peroxide gel is roughly equivalent to a 3.5% hydrogen peroxide gel.
Over-the-Counter vs. Professional Gels: Over-the-counter whitening products generally have lower concentrations than those used by dental professionals. While they may take longer to produce results, they are often a good option for individuals with sensitive teeth.
Selecting the Right Concentration
Start Low: If you're prone to sensitivity, begin with a lower concentration gel (e.g., 6% hydrogen peroxide or 10% carbamide peroxide). You can always increase the concentration later if needed.
Monitor Your Teeth: Pay close attention to how your teeth feel during and after each treatment. If you experience significant sensitivity, reduce the concentration or frequency of treatments.
Professional Guidance
Customised Recommendations: A dentist can assess your teeth and recommend the most appropriate whitening gel concentration based on your individual needs and sensitivity level. They can also provide professional-grade gels with desensitising agents included.
Avoiding Acidic Foods and Drinks
Acidic foods and drinks can erode enamel and further expose the dentinal tubules, increasing the risk of sensitivity during and after teeth whitening. It's important to be mindful of your diet during this time.
Foods and Drinks to Limit or Avoid
Citrus Fruits: Oranges, lemons, grapefruits, and other citrus fruits are highly acidic and can weaken enamel.
Carbonated Drinks: Sodas and sparkling water are also acidic and can contribute to enamel erosion.
Vinegar-Based Dressings: Salad dressings containing vinegar can be harmful to enamel.
Pickled Foods: Pickles and other pickled foods are high in acidity.
Coffee and Tea: While not as acidic as citrus fruits, coffee and tea can still contribute to enamel erosion, especially if consumed frequently.
Enamel-Friendly Alternatives
Water: Staying hydrated with water helps to neutralise acids in the mouth.
Milk: Milk contains calcium and phosphate, which can help to strengthen enamel.
Cheese: Cheese also contains calcium and phosphate and can help to protect teeth from acid attacks.
Vegetables: Crunchy vegetables like carrots and celery can help to stimulate saliva production, which neutralises acids and cleanses the teeth.
Timing Your Meals and Drinks
Avoid Immediately After Whitening: Refrain from consuming acidic foods and drinks for at least an hour after whitening treatments to allow your enamel to recover.
Rinse Your Mouth: If you do consume acidic foods or drinks, rinse your mouth with water afterwards to help neutralise the acids.
Using Fluoride Treatments to Strengthen Enamel
Fluoride is a mineral that helps to strengthen enamel and make it more resistant to acid attacks. Using fluoride treatments can help to reduce sensitivity during and after teeth whitening.
Types of Fluoride Treatments
Fluoride Toothpaste: As mentioned earlier, using fluoride toothpaste is a simple and effective way to strengthen enamel. Look for toothpastes that contain stannous fluoride for added desensitising benefits.
Fluoride Mouthwash: Fluoride mouthwashes can provide an extra boost of fluoride to your teeth. Use them as directed, typically once or twice daily.
Fluoride Varnish: Fluoride varnish is a concentrated fluoride treatment that is applied to the teeth by a dental professional. It forms a protective layer over the enamel and can provide long-lasting protection against sensitivity.
Fluoride Gels: Prescription-strength fluoride gels are available for individuals who are at high risk of tooth decay or sensitivity. These gels are typically applied using a custom-fitted tray.
How Fluoride Strengthens Enamel
Remineralisation: Fluoride helps to remineralise enamel by incorporating itself into the enamel structure, making it stronger and more resistant to acid attacks.
Inhibition of Bacteria: Fluoride can also inhibit the growth of bacteria that cause tooth decay.
Integrating Fluoride into Your Routine
Regular Use: Make fluoride toothpaste and mouthwash a part of your daily oral hygiene routine.
Professional Treatments: Consider professional fluoride treatments, especially if you have a history of sensitivity or tooth decay.
