Whitening treatments for sensitive teeth
A bright, white smile is often associated with good health and attractiveness, which is why many individuals strive to achieve it. However, for those with sensitive teeth, teeth whitening can be a daunting process. Sensitive teeth can cause discomfort or pain during the teeth whitening treatment, discouraging some patients from pursuing it.
The great news is there are professional teeth whitening options available which are specifically designed for individuals with sensitive teeth. Here, we’ll explore the challenges of teeth whitening for sensitive teeth, the benefits of professional treatments, and the options for achieving a brighter smile comfortably.
Causes of tooth sensitivity
Tooth sensitivity is often caused by the exposure of dentin, a layer of the tooth beneath the enamel, which is usually protected. When dentin is exposed, it can cause discomfort and sensitivity, especially when exposed to hot or cold temperatures. Certain factors can cause dentin exposure, including:
- Gum recession: When the gum tissue around the teeth begins to pull back, the roots of the teeth may become exposed, leading to sensitivity.
- Tooth decay: When the protective layer of enamel on the teeth is damaged or eroded, it can expose the dentin and lead to sensitivity.
- Enamel erosion: Acidic foods and drinks, as well as certain medications, can cause enamel erosion on the teeth, leading to sensitivity.
- Cracked or chipped teeth: When teeth are cracked or chipped, the dentin can become exposed and cause sensitivity.
- Overbrushing: Brushing teeth too hard or using a hard-bristled toothbrush can wear away enamel and expose the dentin.
If you have sensitive teeth, you might want to discuss this with your dentist before undergoing professional teeth whitening. Sensitivity can increase during the whitening process, potentially making it uncomfortable and hindering your ability to achieve the desired results.
To minimise discomfort, it’s essential to choose whitening options specifically designed for sensitive teeth. These options are formulated to reduce irritation to both teeth and gums during the whitening process. It’s equally important to avoid any further aggravation of your teeth while undergoing treatment.
Teeth whitening options for sensitive teeth
In-chair teeth whitening
In-chair teeth whitening is popular for patients who want immediate and noticeable results. During an in-chair teeth whitening treatment, a dental professional applies a high-concentration hydrogen peroxide gel to the teeth, which is then activated using a light or laser. The entire process takes about an hour, and you can see a noticeable improvement in the shade of your teeth.
In-chair teeth whitening is a good option for sensitive teeth because the dentist can control the amount of gel and exposure time, minimising discomfort. Additionally, using desensitising agents before and after the treatment can help reduce sensitivity.
Take-home teeth whitening
Take-home teeth whitening involves using custom-made whitening trays filled with a lower concentration of hydrogen peroxide gel. The trays are worn for a specified amount of time each day, typically for two weeks.
Custom-made whitening trays are a good option for sensitive teeth because they provide a more gradual whitening effect, minimising discomfort and sensitivity. Additionally, the trays can be customised to fit the individual’s teeth, reducing the risk of the gel coming into contact with the gums.
Other take-home teeth whitening options, such as whitening strips and paint-on teeth whitening, may also be effective for sensitive teeth, as they use a lower concentration of hydrogen peroxide gel. However, they may take longer to deliver noticeable results than other teeth whitening options.
Light-activated teeth whitening
Light-activated teeth whitening involves using a special light to activate the hydrogen peroxide gel on the teeth. The light helps to accelerate the whitening process and may result in brighter teeth in one treatment.
Light-activated teeth whitening can be a good option for sensitive teeth because it uses a lower concentration of hydrogen peroxide gel and can be customised to the individual’s level of sensitivity.
Tips for avoiding sensitivity during teeth whitening
Professional teeth whitening options for sensitive teeth are designed to minimise discomfort and sensitivity. To further reduce the risk of sensitivity during the whitening process, you can take several steps.
1. Using a desensitising toothpaste can help to reduce sensitivity during teeth whitening. These kinds of toothpaste contain ingredients that help to block nerve signals and reduce sensitivity in the teeth. Using a desensitising toothpaste for several weeks is recommended before starting a teeth whitening treatment.
2. Acidic foods and drinks, such as citrous fruits and juices, can weaken tooth enamel and increase the risk of sensitivity during teeth whitening. It is recommended to avoid acidic foods and drinks before and during the teeth whitening process.
3. Whitening your teeth gradually over several sessions can help to minimise sensitivity. Gradual whitening allows your teeth to adjust to the bleaching agent more slowly, reducing the risk of sensitivity.
4. Using a lower concentration of whitening gel can also help to reduce sensitivity. Many professional teeth whitening options for sensitive teeth offer lower concentrations of bleaching agents or include desensitising agents to minimise sensitivity.
