The smile is the most beautiful accessory, and a sign of confidence and health. However, a few problems can disrupt your smile’s brightness, one of which may be tooth sensitivity. For many, the uncomfortable “zing” that they have reported, is too much to take and it does not hold their interest half way.
The silver lining? You don’t have to accept a listless smile or toothache. Knowing what causes dental sensitivity, and taking a more strategic and gentle approach, you can achieve the shade that you’re looking for without a doubt. You will still get a sexy smile without ruining your enamel and soothing your nerves. Don’t attempt to “whiten” in one big leap, try teeth whitening that looks after you. Here’s a science-based guide for you to be able to learn how to take the art of teeth whitening to a new level.
What causes teeth to become sensitive when they are whitened?
Pain relief is only possible after determining the cause of the pain. Most commercial and DIY whitening products consist of whitening agents, such as hydrogen peroxide or carbamide peroxide. These agents penetrate to the enamel and help break down organic stain trapped in the dentin, the soft layer underneath the hard enamel of the tooth.
They do function but they can temporarily cause dehydration of the teeth, which will leave the tiny tubules, or little canals, open and will open up a direct access to the nerve center of the tooth. When exposed, external stimuli such as cold air, hot coffee or even sugary snacks cause a rapid movement of fluid that stimulates the nerve, causing that dreaded sharp pain. Having thin enamel or receding gums makes you more likely to experience that “whitening ache” as the tubules are already more exposed in your mouth.
The Strategy: A Step-by-Step Plan to Whiter Teeth
People often make the biggest error in being too hasty. Recommending the maximum peroxide concentration for the maximum period of time is to invite severe discomfort. But refrain from the “fast and furious” method – opt for the “slow and steady” way to reach good health.
Focus on your base and build upwards.Do the base first, then build on it!
Before you start using a whitening gel, you have to ensure that your oral health is in good condition. Don’t use whitening as a substitute for cleanliness. Actually, should you have any cavities that haven’t been diagnosed, any leaky fillings or significant gum recession, the whitening agents will only cause you more pain.
Get professional cleaning & assessment. A dentist may be able to identify “hot spots” in your enamel, and suggest specific treatments for those areas. Those who want professional advice should look into clinics such as Nuffield Dental, who explain that the best way to get the aesthetic results you’re looking for without sacrificing comfort is a personalised treatment plan.
Selecting the proper delivery method
Not every whitening will be the same. How sensitive one is will depend on the concentration and placement of the product on teeth. Here are the steps to selecting your method.
| Method | Sensitivity Potential | Best For |
| Whitening Toothpaste | Very Low | Maintenance & Surface Stains |
| Custom-Tray Bleaching | Moderate | Gradual, Controlled Results |
| LED/Light-Activated | High | Fast-Tracked, Intensive Changes |
| Whitening Strips | Moderate-High | Budget-Conscious Users |
Avoid kiosks with high intensity LED systems if you have sensitive teeth. Or have your dentist make special trays. These enable you to utilize a less concentrated peroxide for a longer duration of time and will be much kinder to your tooth structure.
What to look for (and avoid) Key Ingredients
If you’re buying whitening goods, it’s essential to know the ingredients that the product contains or doesn’t contain and make the shopping experience pleasurable or painful. Not all formulas will provide nerve protection.
If you want to see a difference and not be so uncomfortable, choose whitening gels that contain the following desensitising agents:
- Potassium Nitrate: This is the most popular which is used on the nerves in the tooth to relax the nerves and keep them from sending a pain signal to the brain.
- Fluoride: Fluoride is a common component of dentist’s teeth whitening gels. It helps to demineralize enamel, increases its strength and closes off those microscopic channels that allow access to the nerve.
- Amorphous Calcium Phosphate (ACP): A compound that strengthens and restores enamel, fills surface defects. This greatly reduces sensitivity during and after the whitening process.
- Don’t Use High-Acid pH: Don’t use “fast-acting” kits with formulas that are highly acidic, as this softens your enamel, and will ultimately cause an unceasing rise in your likelihood of sensitivity.
These are the ingredients to look for on a label, and you will be able to choose a product which will whiten the surface, but which will also actively soothe the sensitive structures underneath.
Important tips for coping with sensitivity throughout the process
Even with a gentle approach, there will be a little increase in sensitivity for some people. This can typically be managed with appropriate post care.
Apply desensitising Toothpaste BEFORE
Start a whitening treatment two weeks prior to using the desensitising toothpaste that contains potassium nitrate. This is to make sure the microscopic tubules are “plugged” in before the whitening agents are placed upon them.
Divide Your Treatments
If it is recommended that you use it daily, use every other day. The internal fluid pressure in the dentin should be allowed to stabilise after 24 hours between sessions, which greatly minimises the chance of causing a cumulative pain effect.
Avoid Contact with the Gums
Many people mistakenly apply the whitening gel to gum tissue which is not in the appropriate treatment area for bleaching agents. This creates chemical irritation, which spreads to the teeth. Get rid of any excess gel that goes out of your trays or strips immediately.
How to Save Your Enamel, Lifestyle Strategies!
Don’t develop harmful habits that will wear down the enamel or cause staining to set in rapidly, or else you will jeopardize it. Acidic foods and drinks like soda, citrus and wine soften the enamel, making your teeth more porous and sensitive.
Do not over-bleach into the “whitening trap. Once the desired colour has been achieved, stop. Although chronic bleaching may make your teeth whiter, it will gradually compromise the strength of your enamel, and cause persistent sensitivity. Good oral hygiene and periodic full cycle treatments when necessary, not harsh, frequent full cycle treatments.
The concluding words on Radiant Results.
Going on a journey to a brighter smile is an empowering one and not a painful one. Brilliant results with comfortable teeth can be achieved with good care of the enamel, the use of products with controlled delivery systems and listening to your body’s signals. Remember, the best smile is a white smile that stays strong, functions well and is pain free. The key to achieving long term aesthetics in your teeth is consistency and caution.
