A quick zing when you sip something cold. A sharp twinge when the breeze hits your teeth. Sensitivity can be surprisingly disruptive, and it often lingers longer than we expect. The good news is most sensitivity is manageable, and with the right approach, you can get back to enjoying hot coffees and chilly Aperols in the sun without flinching.
What’s actually happening?
Most sensitivity starts when enamel thins or gums recede, exposing the dentine, the layer beneath enamel that contains tiny fluid-filled tubules. Temperature or touch can move the fluid inside those tubules and irritate the nerve. That sensation registers as a quick, sharp pain. The trigger might be cold air, iced drinks, sweet foods, brushing, or even whitening products if your enamel or gums are already a little reactive.
Common causes
Over-brushing or hard bristles
Scrubbing too vigorously or using a hard brush can wear enamel and flatten the gum line.
Acid exposure
Frequent sipping of citrus drinks, wine, soft drink, or kombucha softens enamel. Brushing too soon afterwards can speed up wear.
Gum recession
Gums can gradually recede with age, periodontal irritation, or clenching, exposing the root surface (which is more sensitive).
Grinding or clenching
Night-time grinding (bruxism) creates micro-cracks and wears enamel, increasing sensitivity, especially on biting.
Cracks, chips, or worn fillings
A small crack or an ageing restoration can leak, letting temperature changes reach the nerve more easily.
Post-whitening sensitivity
Whitening can temporarily heighten sensitivity in some people. This is usually short-lived and manageable with the right plan.
Quick relief you can start today
Switch to a desensitising toothpaste
Look for active ingredients like potassium nitrate or stannous fluoride. Use twice daily and don’t rinse straight after brushing—spit and leave a thin layer on your teeth to keep working. Consistency matters; give it two to four weeks.
Go gentle on technique
Use a soft brush, light pressure, and slow circular motions. If you use an electric brush, let it do the work without scrubbing. A pressure sensor can be a game-changer.
Time your brushing
After acidic foods or drinks, wait 30 minutes before brushing. Rinse with water straight away instead.
Adjust your diet rhythm
Keep acidic or sugary sips to mealtimes rather than grazing all day. Follow with water and consider sugar-free gum to stimulate saliva.
Manage grinding
If you wake with jaw tightness, headaches, or flattened tooth edges, mention it. A custom night guard can protect enamel and reduce sensitivity.
In-clinic options that actually help
Fluoride varnishes and desensitising treatments
We can apply concentrated fluoride or specialised varnishes to strengthen enamel and block tubules.
Bonding or sealants
Exposed root surfaces or worn areas can be sealed with a tooth-coloured material to reduce sensitivity.
Treating underlying issues
If a crack, deep decay, or gum disease is behind your symptoms, we’ll address that first. Once the cause is treated, sensitivity usually settles.
Whitening, done thoughtfully If you’re considering whitening and you’re already sensitive, we’ll prep with desensitising products, choose lower concentrations, and build in rest days. A personalised plan keeps your enamel comfortable while still achieving a luminous result.
When to book an appointment
- Sensitivity lingers longer than a few weeks despite desensitising toothpaste
- Pain wakes you at night or is triggered by biting/chewing (possible crack or nerve inflammation)
- You notice bleeding gums, bad breath that won’t shift, or a wobbly tooth
- A filling feels rough, a tooth looks chipped, or a crown feels “high” after recent work
An assessment (The Essential Ritual) is straightforward: we’ll examine your teeth and gums, gently test for triggers, and, if needed, take small, focused X-rays to rule out cracks or decay. You’ll leave with a clear plan and practical steps you can start the same day.
The Sage Space approach
We take sensitivity seriously because comfort changes everything. Our rooms are quiet and unhurried, our explanations are simple, and our treatments are as conservative as possible. Often, the answer is a combination of small adjustments at home plus a quick in-clinic treatment to settle things down.
If sensitivity has been stopping you from enjoying your favourite food or drink, you don’t have to “live with it”. Relief is realistic, and usually closer than you think.
