Teeth and gums hurt: Common causes and what you can do

Why do my teeth and gums hurt?

Tooth and gum sensitivity can be caused by a wide range of issues, most of which link back to poor oral health or brushing technique. Let’s take a closer look at what causes sensitive teeth and gums:

• Plaque build-up: 26% of British adults only brush their teeth once a day.¹ This can lead to a build-up of plaque, a film of bacteria, saliva, and food that covers the teeth, resulting in a wide range of dental issues¹
• Gum inflammation: When you don’t clean away plaque efficiently, it increases inflammation and leads to redness, swelling, and pain in between the gum and tooth.² If left untreated, gum inflammation can develop into more serious gum conditions, including gingivitis.
• Aggressive brushing: Brushing too hard or for too long can wear away your tooth enamel, leading to tooth sensitivity.² Overbrushing is also a leading cause of receding gums, which expose the sensitive roots of your teeth, and can result in bleeding gums.²
• Tooth decay: Bacteria found in plaque can wear away your teeth, leading to tooth decay and cavities.² These can be incredibly painful, increasing sensitivity in the teeth and gums, as well as causing toothaches.

When to take tooth and gum sensitivity seriously

With around 30% of people experiencing tooth sensitivity, this is a fairly common problem, but not one that should be ignored.³

If you struggle with sensitivity when you eat hot or cold foods, for instance, it could be a sign that your enamel is wearing away. Tooth sensitivity at the gumline, on the other hand, is a sign of receding gums, while if the gum between your teeth hurts, you may have gingivitis.³

Fleeting sensitivity isn’t always a cause for concern. If the pain lingers or is frequent, however, it may be best to seek professional dental advice.

How to treat discomfort in teeth and gums

Whether you’re struggling with sore gums between two teeth or ongoing sensitivity, there are steps you can take to relieve discomfort at home. Note that these tips should be accompanied by professional dental care, especially if you’re experiencing persistent pain.

• Floss daily: Flossing before you brush helps remove trapped food particles and bacteria from between the teeth, where irritation and inflammation often start.⁴ This can be particularly helpful if you’re experiencing soreness in one specific area of the gums.
• Brush gently twice a day: Brushing your teeth twice a day for around two minutes helps remove plaque and protect gum health.⁴ However, it’s important to avoid overbrushing, as too much pressure can irritate sensitive gums.

Switching to a sonic toothbrush, like the Philips Sonicare DiamondClean Prestige 9900, can support a gentler yet more effective clean. It removes up to 20x more plaque than a manual toothbrush and helps promote 15x healthier gums in just six weeks.*

The DiamondClean Prestige also features SenseIQ Technology, which detects brushing pressure and automatically adjusts intensity, helping protect teeth and gums from damage caused by overbrushing.

• Use a fluoride toothpaste: A fluoride toothpaste helps strengthen enamel and protect sensitive areas of the teeth.⁴ Regular use can reduce discomfort by making teeth more resistant to acid wear and plaque buildup.
• Rinse with an alcohol-free mouthwash: To address sore, irritated gums around a tooth, follow up with an alcohol-free mouthwash containing chlorhexidine digluconate. This ingredient has been shown to help reduce gingivitis and can be especially useful for sore, swollen gums around a tooth.³

FAQs: Discomfort in teeth and gums

What causes sensitive teeth and gums?

Sensitive teeth and gums are often caused by worn tooth enamel and receding gums, which expose the more sensitive inner layers of the tooth.² These issues are more common when you brush too hard or not often enough, making good dental hygiene a must.

How can I prevent sore gums around teeth?

If the area of gum between your teeth hurts, try rinsing with a chlorhexidine digluconate mouthwash. This acts as a powerful antiseptic to kill bacteria that might be responsible for your sore gums.⁵ You can also try a salt rinse for a simple, at-home solution to reduce bacteria.

How can I stop tooth and gum sensitivity?

If your teeth and gums hurt, your best option is to book a dental appointment. In the meantime, you can try to relieve sensitivity at home by using toothpaste designed for sensitive teeth and brushing gently. You should also switch to the sensitive setting on your DiamondClean Prestige 9900 toothbrush and use the built-in pressure sensor to improve your technique.

From sensitivity to pain in between your gum and tooth, dental issues are never fun to deal with. These early warning signs, though, are often your mouth’s way of asking for a little extra care, giving you the push to take action before small issues turn into bigger problems. Take discomfort in teeth and gums seriously and feel confident that you’re taking control of your oral health for the long term.
