Many people experience sensitive teeth – whether it’s a sudden twinge when enjoying something cold, or a lingering ache after a hot drink. At Toothcare Dental in Wigmore, Gillingham, we help patients understand what’s causing their sensitivity and offer effective treatments to keep your teeth healthy and protected.
Tooth sensitivity (or dentine hypersensitivity) occurs when the protective enamel layer on the outside of the tooth, becomes thinner or when the gums recede, exposing the underlying dentine. This dentine contains tiny tubules that lead directly to the nerve. When exposed, everyday sensations such as cold air, sweet foods or hot drinks can trigger sharp, sudden discomfort.
Enamel Erosion
Acidic foods, fizzy drinks, stomach acid (reflux), or brushing too hard can gradually wear down the protective layer of enamel.
Gum Recession
As gums pull back, the root surface becomes exposed. This area isn’t protected by enamel and is much more sensitive.
Tooth Grinding (Bruxism)
Clenching or grinding can weaken enamel and cause micro-fractures, leading to sensitivity.
Tooth Decay or Damaged Fillings
Holes, cracks, or failing restorations expose the dentine and nerves.
Whitening Sensitivity
Some patients notice temporary sensitivity during or after teeth whitening treatments.
Gum Disease
Inflammation or infection around the gums can increase sensitivity and discomfort.
Use a Desensitising Toothpaste
These toothpastes help block the tiny tubules in the dentine that lead to the nerve. With regular use, sensitivity often reduces within a few weeks.
Switch to a Soft-Bristled Toothbrush
Brushing too firmly or using a hard brush can wear away enamel. A gentle brush - combined with good technique - helps protect tooth surfaces.
Avoid Acidic Foods and Drinks
Fizzy drinks, citrus fruits, wine and energy drinks soften enamel. Limiting these (or rinsing with water after consuming them) helps protect your teeth.
Reduce Teeth Grinding
If you grind at night, managing stress and avoiding chewing hard items (like pens or ice) can help until you see us for a night guard.
Use Fluoride Mouthwash
A daily fluoride rinse can strengthen enamel and reduce sensitivity over time.
Warm, Not Hot or Cold, Drinks
Switching to lukewarm drinks can help avoid sudden temperature changes that trigger sensitivity.
A tooth-coloured resin covering protects exposed dentine and reduces sensitivity almost immediately. Learn more about composite bonding
If sensitivity is linked to worn or thin enamel on the front surface of your teeth, porcelain veneers may help by providing a protective new outer layer. Veneers can reduce sensitivity by shielding the tooth from temperature changes while also improving the appearance of your smile. They are not suitable when sensitivity is caused by gum recession or issues affecting the root, but they can be a good option for patients looking to address both sensitivity and cosmetic concerns.

If gum recession or gum disease is the cause, professional hygienist cleaning and targeted periodontal care can help restore gum health.
If grinding is wearing down your enamel, we can create a tailored night guard to protect your teeth while you sleep.
For sensitivity caused by decay or damaged fillings, we can provide:
All of these treatments can help to seal and protect the tooth structure.
When sensitivity progresses into nerve pain or infection, root canal therapy may be necessary to save the tooth and remove the source of pain. Find out more about root canal treatment
Sensitivity is often treatable and shouldn’t be ignored - early care prevents bigger problems occurring later.
Based in Wigmore, Gillingham, Toothcare Dental provides gentle, personalised care for patients across Medway, including Gillingham, Sittingbourne, Chatham and Maidstone. Whether your sensitivity is new or long-standing, our experienced team can diagnose the cause and recommend the most effective treatment.
Sensitive teeth are usually caused by worn enamel, gum recession, tooth decay, grinding, or exposed dentine. When the protective layers of the tooth are weakened, sensations like cold air or sweet foods can reach the nerve more easily.
Mild sensitivity may improve with good home care, such as using desensitising toothpaste. However, if the enamel is worn or the dentine is exposed, the problem won’t resolve on its own and professional treatment is often needed.
Yes, if sensitivity lasts more than a few days, affects one tooth in particular, wakes you at night, or is getting worse. These signs often point to an underlying issue such as decay, gum recession or a cracked tooth.
The right treatment depends on the cause. Options include fluoride varnish, composite bonding, gum treatment, bite guards for grinding, restorative work (fillings or crowns) and in some cases veneers. For severe sensitivity, a root canal may be required.
Veneers can help reduce sensitivity when enamel on the front surface of the tooth is worn or thin. They provide a protective new layer. However, they won’t help if the sensitivity is caused by gum recession or root exposure.
Sometimes, yes. Persistent sensitivity can be a sign of decay, cracks, gum disease or significant enamel wear. Early diagnosis prevents the problem progressing into pain or infection.
