How to Prevent Teeth Sensitivity After Using Whitening Strips

Posted on by

Teeth whitening strips are a popular and convenient method for achieving a brighter smile. However, one of the most common side effects of using whitening strips is teeth sensitivity. This sensitivity can range from mild discomfort to significant pain and can deter some individuals from continuing their whitening treatment. Fortunately, there are several strategies to prevent and manage teeth sensitivity after using whitening strips. This comprehensive guide will explore the causes of teeth sensitivity, provide preventive measures, and offer tips for managing discomfort, ensuring a more comfortable whitening experience.

Understanding Teeth Sensitivity

Related Posts

Teeth sensitivity, also known as dentin hypersensitivity, is characterized by discomfort or pain in response to certain stimuli, such as hot, cold, sweet, or acidic foods and beverages. This condition occurs when the dentin, the layer beneath the enamel, becomes exposed due to enamel erosion or gum recession.

Causes of Teeth Sensitivity After Whitening

  • Peroxide Penetration: Teeth whitening strips contain peroxide-based agents, such as hydrogen peroxide or carbamide peroxide. These agents penetrate the enamel and dentin, releasing oxygen to lift stains. However, this process can also increase the porosity of the enamel and dentin, allowing stimuli to reach the nerves more easily.
  • Enamel Erosion: The whitening process can temporarily soften the enamel, making it more susceptible to erosion and sensitivity.
  • Gum Recession: In some cases, whitening strips can irritate the gums, leading to recession and exposing the sensitive root surfaces of the teeth.
  • Pre-existing Sensitivity: Individuals with pre-existing teeth sensitivity may experience heightened discomfort after using whitening strips.

Mechanism of Teeth Whitening Strips

Teeth whitening strips work by delivering a peroxide-based gel to the tooth surface. The peroxide penetrates the enamel and dentin, releasing oxygen, which then reacts with the stain molecules, breaking them apart and lifting them off the tooth surface. This process is known as oxidation. However, the same process that lifts stains can also cause temporary sensitivity by increasing the porosity of the enamel and dentin.

Preventing Teeth Sensitivity Before Whitening

I recommend you try personal care product:

Consult Your Dentist

Before starting any whitening treatment, consult your dentist to rule out underlying dental issues that may cause or worsen sensitivity, such as cavities or gum disease. Your dentist can provide personalized advice and recommend appropriate whitening options for your dental health.

Use Desensitizing Toothpaste

Brush your teeth with a desensitizing toothpaste for at least two weeks before starting the whitening treatment. Desensitizing toothpastes contain ingredients like potassium nitrate or stannous fluoride, which help to soothe nerves and reduce sensitivity.

Recommended desensitizing toothpastes:

  • Sensodyne Repair & Protect
  • Colgate Sensitive Pro-Relief
  • Crest Sensi-Stop Strips

Maintain Good Oral Hygiene

Ensure that your teeth and gums are healthy by maintaining good oral hygiene practices. Brush your teeth gently with a soft-bristled toothbrush and fluoride toothpaste, and floss daily to remove plaque and prevent gum disease.

Get a Professional Cleaning

Schedule a professional dental cleaning before starting your whitening treatment. A cleaning can remove built-up plaque and tartar, ensuring that the whitening agent can make direct contact with the tooth surface and reducing the risk of gum irritation.

Apply Fluoride

Apply a thin layer of fluoride gel or varnish to your teeth before starting the whitening treatment. Fluoride helps to strengthen enamel and reduce sensitivity. You can purchase fluoride gel over the counter or ask your dentist for a professional fluoride treatment.

Choosing the Right Teeth Whitening Strips

Selecting the appropriate teeth whitening strips is crucial for minimizing sensitivity and maximizing comfort. Consider the following factors:

  • Peroxide Concentration: Strips with lower peroxide concentrations (e.g., 3-6%) are gentler on sensitive teeth. While they may take longer to achieve the desired results, they are less likely to cause significant discomfort.
  • Enamel-Safe Formulations: Look for strips with added ingredients like potassium nitrate, which helps to soothe nerves and reduce sensitivity, and fluoride, which strengthens enamel.
  • Treatment Duration: Strips designed for shorter application times (e.g., 5-10 minutes per day) can minimize sensitivity compared to those requiring longer application times.

Recommended teeth whitening strips for sensitive teeth:

  • Crest 3D White Gentle Routine Whitestrips
  • Listerine Healthy White Gentle Whitening Strips
  • Spotlight Oral Care Dental Teeth Whitening Strips

Preventing Teeth Sensitivity During Whitening

Gradual Approach

Start with a lower concentration of peroxide and gradually increase it as your teeth become more tolerant. This gradual approach can help minimize sensitivity while still achieving the desired whitening results.

Reduce Treatment Time

If you experience significant sensitivity, reduce the application time of the strips. You can also space out your treatments, using the strips every other day instead of daily.

Use Sensitivity Relief Products

In addition to desensitizing toothpaste, consider using sensitivity relief mouth rinses or gels. These products contain ingredients that help to soothe nerves and reduce discomfort.

Recommended sensitivity relief products:

  • Colgate Sensitive Pro-Relief Mouthwash
  • Sensodyne Pronamel Mouthwash
  • Orajel Severe Toothache & Gum Relief

Apply Fluoride

Apply a thin layer of fluoride gel or varnish to your teeth before and after using whitening strips. Fluoride helps to strengthen enamel and reduce sensitivity.

Avoid Extreme Temperatures

Be mindful of consuming very hot or cold foods and beverages, as these can exacerbate sensitivity. Opt for lukewarm or room-temperature items during your whitening treatment.

Chew Sugar-Free Gum

Chewing sugar-free gum can help to stimulate saliva production, which in turn can help to remineralize enamel and reduce sensitivity. Look for gum containing xylitol, a natural sweetener that promotes saliva production and has oral health benefits.

Post-Whitening Care

Continue Using Desensitizing Toothpaste

Continue using desensitizing toothpaste for at least two weeks after completing your whitening treatment. This will help to minimize sensitivity and promote enamel remineralization.

Avoid Staining Agents

For at least 24 hours after treatment, avoid foods and beverages that can stain your teeth, such as coffee, tea, red wine, and dark-colored fruits. Additionally, avoid acidic foods and beverages, as they can increase sensitivity.

Maintain Good Oral Hygiene

Continue brushing and flossing regularly to maintain the results and prevent new stains from forming. Use a soft-bristled toothbrush and gentle brushing technique to avoid irritating the gums and causing recession.

Consider a Fluoride Rinse

Incorporate a fluoride mouth rinse into your daily oral care routine to help strengthen enamel and reduce sensitivity. Look for a rinse containing sodium fluoride, which is known for its enamel-strengthening properties.

Recommended fluoride mouth rinses:

  • ACT Anticavity Fluoride Mouthwash
  • Listerine Healthy White Fluoride Mouthwash
  • Colgate Phos-Flur Rinse

Regular Dental Check-ups

Regular dental check-ups and professional cleanings can help maintain your teeth’s health and brightness. Dentists can also provide personalized advice on whitening treatments and oral hygiene.

Managing Teeth Sensitivity After Whitening

If you experience teeth sensitivity after using whitening strips, there are several strategies to manage the discomfort and promote oral healing.

Take Over-the-Counter Pain Relievers

Over-the-counter pain relievers such as ibuprofen or acetaminophen can help to alleviate sensitivity-related discomfort. Follow the instructions on the packaging for proper dosage and usage.

Apply Topical Anesthetics

Topical anesthetics containing benzocaine or lidocaine can help to numb the affected area and provide temporary relief from sensitivity. Apply a small amount of the anesthetic to the sensitive tooth using a cotton swab.

Recommended topical anesthetics:

  • Orajel Maximum Strength Toothache & Gum Relief
  • Anbesol Maximum Strength Oral Anesthetic
  • Oragel Instant Pain Relief

Use a Salt Water Rinse

A salt water rinse can help to reduce inflammation and promote healing. Mix 1/2 teaspoon of salt with 8 ounces of warm water, and swish the solution around your mouth for 30 seconds before spitting it out. Repeat this process several times a day until the sensitivity subsides.

Apply a Cold Compress

Applying a cold compress to the outside of your cheek can help to numb the affected area and reduce discomfort. Wrap an ice pack in a towel and apply it to your cheek for 15-20 minutes at a time, taking breaks in between to avoid frostbite.

Avoid Whitening for a While

If you experience significant sensitivity, take a break from whitening treatments to allow your teeth to recover. Resume whitening once the sensitivity has subsided, and consider using a lower concentration of peroxide or reducing the application time.

Consider Professional Desensitizing Treatments

If at-home remedies are not providing adequate relief, consult your dentist about professional desensitizing treatments. These treatments may include:

  • Fluoride Varnish: A professional fluoride varnish treatment can help to strengthen enamel and reduce sensitivity.
  • Bonding Agent: A bonding agent can be applied to the sensitive areas of the tooth to create a barrier and protect the nerve endings.
  • Gum Graft: In cases of gum recession, a gum graft can be performed to cover the exposed root surfaces and reduce sensitivity.

Alternative Whitening Methods for Sensitive Teeth

If teeth whitening strips cause significant discomfort, consider alternative whitening methods designed for sensitive teeth.

Custom Whitening Trays

Custom whitening trays are made by your dentist to fit your teeth precisely. These trays use a lower concentration of peroxide and can be worn for shorter durations, minimizing sensitivity.

In-Office Whitening

In-office whitening treatments use professional-grade peroxide gels and are monitored by a dentist. These treatments can achieve significant whitening results in a single visit, and your dentist can take precautions to minimize sensitivity.

Whitening Toothpaste and Mouthwash

Whitening toothpastes and mouthwashes contain lower concentrations of peroxide and are gentler on sensitive teeth. While they may take longer to achieve the desired results, they are less likely to cause significant discomfort.

Recommended whitening toothpastes and mouthwashes for sensitive teeth:

  • Sensodyne Pronamel Gentle Whitening Toothpaste
  • Colgate Sensitive Whitening Toothpaste
  • Listerine Healthy White Gentle Whitening Mouthwash

Natural Whitening Remedies

Some natural remedies can help to whiten teeth gently. However, these methods may not be as effective as peroxide-based treatments. Always consult your dentist before trying any natural whitening remedies.

  • Oil Pulling: Swish coconut oil around your mouth for 15-20 minutes, then spit it out and brush your teeth. Oil pulling can help to remove surface stains and promote oral health.
  • Baking Soda: Mix baking soda with water to create a paste, and brush your teeth with the mixture. Baking soda is a mild abrasive that can help to remove surface stains.
  • Activated Charcoal: Brush your teeth with activated charcoal powder or use a toothpaste containing activated charcoal. Activated charcoal can help to absorb and lift surface stains.

Maintaining Your Bright Smile

Limit Staining Agents

Limit your intake of foods and beverages known to stain teeth. If you do consume these items, rinse your mouth with water afterward to minimize staining.

Foods and beverages to limit:

  • Coffee
  • Tea
  • Red wine
  • Dark-colored fruits (e.g., berries, pomegranates)

Maintain a Whitening Routine

To keep your teeth looking their best, incorporate a regular whitening routine into your oral care regimen. This might include using whitening toothpaste, mouthwash, and periodic use of whitening strips designed for sensitive teeth.

Protect Your Enamel

Maintain good oral hygiene practices and use products that strengthen enamel, such as fluoride toothpaste and mouth rinses. Strong enamel is less prone to sensitivity and staining.

Regular Dental Check-ups

Regular dental check-ups and professional cleanings can help maintain your teeth’s health and brightness. Dentists can also provide personalized advice on whitening treatments and oral hygiene.

When to See a Dentist

While some degree of teeth sensitivity is normal after using whitening strips, certain symptoms may indicate a more serious underlying issue. Contact your dentist if you experience any of the following:

  • Severe, persistent pain that does not improve with over-the-counter pain relievers
