Have you always dreamt of having a sparkling, bright white smile? Discolouration is one of the main reasons people feel self-conscious about their smile; it’s also one of the most straightforward things to change. That’s why teeth whitening is one of the most popular treatments at our Fulham dental practice.


A bright, radiant smile is a goal for many of our patients, and professional teeth whitening in Fulham is a safe and effective way to achieve it. But, once whitening treatment is complete, some patients come to us asking, “why are my teeth sensitive after whitening?".


If you’ve been wondering about your own sensitivity post-whitening, or you’ve heard that whitening can cause sensitivity and are curious to know why, look no further. In this blog, we’ll delve into the reasons behind teeth sensitivity post-whitening and provide valuable insights on how to manage and minimise it.


Understanding teeth whitening in Fulham

Teeth whitening is a popular cosmetic dental procedure designed to remove stains and discolouration from the teeth, resulting in a visibly whiter smile. It can be performed either in-office at a dental practice or with take-home kits.


Beware over-the-counter whitening products! Professional teeth whitening in Fulham is the most reliable and effective option, as over-the-counter products can damage your precious tooth enamel and cause significant sensitivity.


Common causes of teeth sensitivity after whitening

To address sensitivity after teeth whitening, it's essential to understand the common causes. Several factors can contribute to the sensitivity you may experience post-whitening:

  • Whitening gel concentration: The concentration of the whitening gel used during the procedure plays a significant role in sensitivity. Stronger gels can produce more immediate results but may also lead to increased sensitivity. At New Smile Fulham, our experienced dentists carefully select the appropriate gel concentration based on your unique needs, aiming to minimise any potential discomfort.

  • Tooth dehydration: During teeth whitening, the enamel temporarily loses moisture, leading to tooth dehydration. This can make the teeth more susceptible to sensitivity, especially in the immediate aftermath of the treatment.

  • Gum irritation: If the whitening gel comes into contact with your gums, it can cause irritation and lead to sensitivity. Our dental professionals take extra care to protect your gums during the teeth whitening procedure to prevent such issues.

  • Existing dental issues: If you have underlying dental problems like cavities, gum disease, or cracked teeth, teeth whitening can exacerbate sensitivity. It is essential to address these issues before considering teeth whitening to avoid complications.

  • Overuse of whitening products: Overusing whitening products, whether professional or over-the-counter, can weaken the enamel and cause sensitivity. At New Smile Fulham, our team provides guidance on the appropriate frequency and duration of teeth whitening to maintain your oral health.


Managing teeth sensitivity after whitening

If you're experiencing sensitivity after teeth whitening in Fulham, here are some tips on how to manage and alleviate the discomfort:


Use toothpaste for sensitive teeth

Toothpaste formulated for sensitive teeth contains desensitising agents that help block pathways from the tooth's surface to the nerve. Using this type of toothpaste regularly can ease sensitivity.


Avoid extremely hot or cold foods

After teeth whitening, steer clear of extremely hot or cold foods and drinks for a few days, as they can trigger sensitivity. Opt for lukewarm or room temperature options.


Stay hydrated

Drinking plenty of water and staying well-hydrated can help reduce sensitivity by preventing tooth dehydration.


Use a soft-bristled toothbrush

Switch to a soft-bristled toothbrush to minimise abrasion on your teeth and gums. Gently brush your teeth using fluoride toothpaste.


Take over-the-counter pain relievers

As a short-term solution, non-prescription pain relievers like ibuprofen or paracetamol can help manage sensitivity. Be sure to consult your dentist before taking any medication.


Gel trays

If you received professional teeth whitening at New Smile Fulham, your dentist may provide gel trays with a desensitising gel. Applying this gel can alleviate sensitivity and strengthen your enamel.


Consult your dentist

If your teeth sensitivity persists or worsens, it's essential to consult your dentist. Our experienced team can examine your oral health and provide tailored guidance on how to address the issue effectively.


Start your journey with teeth whitening in Fulham

We understand that teeth sensitivity after whitening can be a concern, but it's essential to remember that it's a temporary side effect for many individuals. As our patients say, the benefits of having a brighter and more confident smile often outweigh the brief discomfort.
