Applying Paste to a Sensitive Spot
Short answer. To apply paste to a sensitive spot, brush it on gently with a soft brush as part of your normal twice-daily routine, rather than rubbing it hard into the tooth. Use the amount the tube directs, cover the whole mouth as usual, and let the paste stay on the sensitive area for a moment before spitting.
- Brush the sensitive area gently, not harder.
- Use sensitivity paste as your regular toothpaste, not as a spot treatment alone.
- Follow the amount and directions printed on the tube.
- Spit out the excess and avoid rinsing straight away.
- A spot that stays painful needs a dentist, not more paste.
What does it mean to apply paste to a sensitive spot?
Most people picture dabbing paste on one painful tooth. In practice, sensitivity toothpaste is meant to be used for ordinary brushing, with a little extra time given to the area that bothers you. The paste is made to be used across the whole mouth, twice a day, in the same way as any other toothpaste.
Some tubes mention applying a small amount with a clean fingertip to a sensitive area. That is the manufacturer's own direction, so read the leaflet or box and follow it rather than improvising.
A step-by-step checklist for brushing
Start with a soft-bristled brush and the amount of paste the packaging suggests. Tilt the bristles towards the gumline and use short, light strokes, spending a few extra seconds on the sensitive spot without pressing hard.
Finish by spitting out the excess. Many dental organisations advise spitting rather than rinsing, so that the paste ingredients stay on your teeth a little longer.
- Soft brush, light pressure
- Pea-sized or as directed on the tube
- Angle bristles gently towards the gumline
- Extra few seconds on the sensitive area
- Spit, do not rinse straight away
Mistakes that make sensitivity feel worse
Pressing hard is the big one. Scrubbing can wear away enamel and irritate receding gums, which are often part of why a spot is sensitive in the first place. Brushing very soon after acidic drinks or fruit can also be rough on softened enamel, so waiting a while is usually kinder.
Another common slip is using the paste only on bad days. Dabbing it on after a twinge starts is less in keeping with how these products are designed to be used, which is regularly.
Should you use your finger?
Fingertip application appears in the directions of some products and not others. If your tube suggests it, wash your hands first and use a small amount on the sensitive area, as directed. If it does not mention it, brushing normally is the safer default.
A dentist or pharmacist can tell you whether a fingertip method suits the product you are using.
When one spot keeps hurting
A single tooth that stays sore, aches after a cold drink has gone, or hurts when you bite deserves a dental check. Cracks, worn fillings, early decay and gum recession can all feel like sensitivity, and paste cannot fix the underlying cause.
Also see a dentist for swelling, bleeding gums that do not settle, a loose tooth or a bad taste that will not go away.
One optional extra, kept in perspective
Some readers wonder about oral probiotic supplements. ProDentim is one example: the seller says it is a chewable oral probiotic taken each morning and lists three strains, Lactobacillus paracasei, Bifidobacterium lactis BL-04 and Lactobacillus reuteri. These are the seller's claims and are not verified here, and research on oral probiotics is still early and mixed. Anyone pregnant, breastfeeding, on medication or with a medical condition should ask a dentist, doctor or pharmacist first. It is no substitute for brushing technique or a dental check.
Questions readers ask
How much paste should I put on the brush?
Follow the amount printed on the tube or box. For adults that is commonly a pea-sized amount, though some products give their own guidance.
Can children use sensitivity toothpaste?
Ask a dentist or pharmacist first. Sensitivity in a child is worth a dental check, and the right paste and amount depend on age.
Does it matter whether I brush before or after breakfast?
Many people find it kinder to wait a while after acidic food or drink before brushing. Your dentist can suggest timing that suits your routine.
Is a bristle type important?
Soft bristles are what dental organisations commonly advise, especially if your teeth are sensitive or your gums have receded.
Talk to a professional. Persistent bleeding, pain, swelling, loose teeth or sores that do not heal need a dentist's attention, not a supplement.
