How to brush sensitive teeth: Gentle practices that protect your teeth

Why sensitive teeth brushing can cause discomfort

Tooth sensitivity usually occurs when the protective enamel layer becomes thinner or when gums recede slightly, exposing the dentine underneath.¹ Dentine contains microscopic channels that connect to the nerve of the tooth, which is why sensitivity when brushing can feel sudden and sharp.²

Several common factors can contribute to tooth sensitivity when brushing, including¹²:

• Brushing too aggressively
• Using a toothbrush with very firm bristles
• Acidic foods and drinks gradually weakening enamel
• Gum recession exposing more of the tooth surface

When these factors combine, people sometimes reach a point where their teeth are too sensitive to brush comfortably. Skipping brushing might feel tempting, but maintaining good oral hygiene remains essential.

Choosing the right tools for sensitive teeth

The tools you use can make a significant difference when brushing sensitive teeth. A toothbrush that applies too much pressure or uses stiff bristles may worsen discomfort so it can help to choose one designed for gentle, controlled cleaning.²

Electric toothbrushes with pressure feedback and adjustable intensity settings can be particularly useful, as they help you clean effectively without relying on heavy pressure. For example, the Philips Next-Generation DiamondClean 9900 Prestige uses SenseIQ adaptive intensity, which automatically adapts the brushing intensity if you press too hard. It also provides smart pressure feedback, helping guide you towards a gentler brushing technique in real time.

For those choosing between brushes, it may help to look for features such as:

• Pressure feedback to alert you when you are brushing too hard
• Adjustable intensity levels to make brushing feel more comfortable
• Gentle cleaning modes that still support effective plaque removal
• App or post-brushing feedback to help improve your technique over time

Another option is the Philips Next-Generation DiamondClean 8500, which also offers smart pressure feedback and adjustable brushing settings. This can help support sensitive teeth brushing without the need for excessive pressure.

Choosing a toothbrush with gentle cleaning modes, pressure feedback and intensity control can make brushing feel more comfortable for those whose teeth are too sensitive to brush using traditional methods.

How to brush sensitive teeth properly

If brushing teeth hurts, adjusting your technique can often make brushing much more comfortable. The goal is to clean thoroughly without applying unnecessary pressure.

Here is a simple guide showing how to brush sensitive teeth properly³:

1. Hold the toothbrush at a 45-degree angle: Position the brush so it gently reaches the gumline without pushing into it.
2. Use light pressure: Let the brush do the work. Pressing harder does not clean better and may worsen tooth sensitivity when brushing.
3. Brush for two minutes: Divide your mouth into four sections and spend around thirty seconds on each quadrant.
4. Choose toothpaste designed for sensitivity: Desensitising toothpaste can help block nerve signals and reduce discomfort over time.
5. Replace worn toothbrush heads: Old brush heads can become rough and less effective.

Practical tips for caring for sensitive teeth

Beyond brushing technique, everyday habits also play an important role in how to take care of sensitive teeth.

The following habits can help reduce discomfort and support caring for sensitive teeth¹²:

• Use desensitising toothpaste regularly
• Avoid brushing immediately after acidic foods
• Use a soft or extra soft brush head
• Reduce highly acidic drinks such as fizzy beverages
• Maintain consistent brushing twice a day

These small adjustments can make sensitive teeth brushing much more comfortable over time.

It is also important not to brush too aggressively. Excess pressure can contribute to enamel wear and gum irritation.¹

When to seek professional advice

Occasional sensitivity is common, but persistent discomfort may signal a larger issue. If you often find yourself thinking “my teeth are sensitive when I brush them”, it may be worth discussing symptoms with a dentist.

Persistent tooth sensitivity when brushing could sometimes be linked to gum disease, enamel erosion or untreated cavities.¹ A dentist can help identify the cause and recommend appropriate treatment.

Maintaining gentle brushing habits while seeking advice can help ensure your teeth remain clean and protected.
