Sensitive Teeth and Receding Gums: Causes, Symptoms, and the Best Ways to Treat Them

Sensitive teeth and receding gums are two of the most common oral health concerns among adults especially those aged 30 and above. While the discomfort may come and go, untreated sensitivity and gum recession can progress into more serious issues such as chronic inflammation, enamel loss, and even tooth mobility. The good news? With the right oral care routine and awareness of early signs, both conditions can be managed effectively.

In this guide, we explore the causes, warning signs, treatments, and prevention tips for sensitive teeth and receding gums, as well as how a gentle, enzyme-based toothpaste can support long-term oral defence.

What Causes Sensitive Teeth?

Tooth sensitivity occurs when the protective enamel layer wears down or when gums recede, exposing the dentine, a porous layer filled with microscopic tubules that lead directly to the nerves. When dentine is exposed, triggers such as cold drinks, sweet foods, or even brushing can cause sharp, sudden pain.

Common causes of tooth sensitivity

• Receding gums exposing the root surface

• Aggressive toothbrushing

• Acidic foods and drinks wear down enamel

• Teeth grinding (bruxism)

• Gum disease

• Overuse of whitening products

• SLS-based toothpaste irritation (Sodium Lauryl Sulphate can damage oral tissues)

Why Do Gums Recede?

Gums recede when the tissue around your teeth begins to pull away. This exposes the root surface, which does not have enamel protection, leading to heightened sensitivity and increased risk of decay.

Main causes of gum recession

• Gum disease (gingivitis and periodontitis)

• Genetic predisposition

• Brushing too hard or using a hard-bristle toothbrush

• Hormonal changes

• Smoking

• Poor oral hygiene

• Ageing gum recession becomes more common over 40

Studies show that 47.2% of adults over 30 have some type of gum disease, which directly contributes to gum recession.

Symptoms to Look Out For

You may be experiencing sensitive teeth or receding gums if you notice:

• Sharp, sudden pain when eating or drinking hot/cold foods

• Pain when brushing or flossing

• Visible long-tooth appearance

• Gum line pulling away

• Occasional bleeding when brushing

• Persistent bad breath

If gum disease is involved, symptoms like swelling, redness, and tenderness may also be present.

How to Treat Sensitive Teeth and Receding Gums

1. Use a toothpaste with desensitising agents

Potassium nitrate is one of the most effective and widely recognised ingredients for relieving sensitivity. It works by calming the nerve fibres inside the tooth, reducing pain signals over time. Enzim 40 Plus Toothpaste contains potassium nitrate and silica, offering gentle relief for sensitive teeth.

2. Switch to an SLS-free toothpaste

SLS (Sodium Lauryl Sulphate) can irritate the mouth, roughen tooth surfaces, and disrupt the oral microbiome. This increases plaque retention, which worsens gum recession and sensitivity.

Choosing an SLS-free toothpaste helps maintain a healthy oral environment and reduces irritation.

3. Strengthen saliva’s natural defence

A strong oral defence system relies on saliva quality. Enzyme-based toothpaste supports this by restoring natural antibacterial protection. The combination of enzymes such as Amyloglucosidase, Glucose Oxidase, Lactoperoxidase, Lysozyme, and Lactoferrin helps reduce harmful bacteria and support gum health.

4. Professional dental cleaning

Regular scaling and polishing removes plaque and tartar that contribute to gum disease.

5. Gum disease treatment

Your dentist may prescribe deep cleaning (root planing), antibiotics, or other gum therapy.

6. Avoid aggressive brushing

Use a soft-bristle toothbrush and gentle pressure.

7. Reduce acidic food intake

Acids soften enamel and increase dentine exposure.

Can Receding Gums Grow Back?

Unfortunately, once gum tissue is lost, it does not naturally grow back. However, you can prevent further recession and strengthen your gum health through:

• Excellent oral hygiene

• Enzyme-based, SLS-free toothpaste

• Managing inflammation

• Treating gum disease early

• Avoiding habits that damage gums

In advanced cases, dentists may recommend gum grafting to restore lost tissue.

Best Oral Care Routine for Sensitive Teeth and Receding Gums

• Brush twice daily with a gentle, SLS-free, enzyme-based toothpaste

• Use desensitising toothpaste with potassium nitrate

• Floss daily to remove plaque from the gum line

• Rinse with an alcohol-free mouthwash

• Visit your dentist every 6 months

• Limit sugary and acidic snacks
