Discover the causes of pain and the best treatments to end daily discomfort.
Por Dra. Camila, Cirurgiã-Dentista
Have you ever felt that shock in your teeth when eating ice cream or drinking hot coffee? This sensation, which may seem fleeting, is called tooth sensitivity and affects millions of people. While common, it shouldn’t be ignored, as it’s often a sign of enamel wear, gum recession, or even cavities.
The good news is that there are practical, quick and safe ways to relieve tooth sensitivity, from simple routine changes to professional treatments at the dentist’s office.
What to do to relieve tooth sensitivity
The first step is to understand the cause of the sensitivity. It can be the result of brushing too hard, using a hard-bristled toothbrush, gum recession, bruxism, or frequent consumption of acidic foods.
To ease your daily stress, make small changes:
- Use a soft-bristled brush.
- Switch to a toothpaste specifically for sensitive teeth.
- Reduce your intake of soft drinks, acidic fruits, and very cold drinks.
- Never forget to floss, but without excessive force.
These precautions already make a difference in the first few weeks.
Dental sensitivity in special situations:
- Pregnancy: Hormonal changes can increase sensitivity.
- Systemic diseases: Diabetes and osteoporosis can have an influence.
Tips for relieving pain:
- Avoid foods and drinks that are too hot, cold, acidic or sweet.
- Use straws for cold drinks.
- Use products for sensitive teeth.
How to get rid of tooth sensitivity quickly
Many people seek immediate solutions, especially when the pain is severe. In this case, some strategies can speed up relief:
- Use toothpaste with potassium nitrate or arginine.
- Rinse your mouth with alcohol-free mouthwash.
- Consult your dentist to apply high-concentration fluoride.
These measures can provide improvement in a few days, but it is important to maintain your prevention routine.
Best Toothpastes for Sensitive Teeth 2025
Choosing the right toothpaste is essential for those who suffer from sensitive teeth. In 2025, the most recommended toothpastes are:
- Sensodyne Repair & Protect – restaura áreas vulneráveis.
- Colgate Sensitive Pro-Relief – acts directly on the dentin canals.
- Oral-B Sensitivity and Gums – protects against pain and inflammation.
Use should be daily and continuous, for at least 2 to 4 weeks, for consistent results.
What is good for sensitive toothache at home?
It’s not always possible to rush to the dentist immediately, but some home care can help:
- Brush your teeth gently, without pressing.
- Avoid cold and very acidic drinks during the crisis.
- Apply a sensitivity toothpaste directly to the painful area and let it sit for a few minutes before rinsing.
These measures provide temporary relief, but are not a substitute for professional assessment.
Treatment for tooth sensitivity without surgery
Many cases can be resolved without surgery. The most common treatments are:
- In-office fluoride application to strengthen enamel.
- Desensitizing sealants and varnishes, which block painful stimuli.
- Occlusal splints for those who suffer from bruxism.
These procedures are quick, painless and effective.
Why do my teeth hurt when I drink cold water?
Pain when eating cold foods occurs because the dentinal tubules—tiny canals inside the teeth—are exposed. When the enamel is worn or the gums recede, these stimuli reach the nerve, causing a painful shock.
If the problem persists, it could indicate cavities or even cracked teeth that need immediate attention.
How to treat tooth sensitivity due to gum recession
Gum recession is one of the most common causes of sensitivity. It occurs when the gums “rise” and expose the tooth root, which lacks protective enamel.
Treatment may include:
- Adjustments in brushing to prevent further retraction.
- Toothpastes for sensitive teeth.
- Periodontal treatments in the office.
- In more advanced cases, gum resurfacing surgery.
The sooner the downturn is identified, the greater the chances of recovery.
Habits that help prevent tooth sensitivity
- Choose soft-bristled brushes.
- Do not use force when brushing your teeth.
- Reduce your consumption of soft drinks, wines and very acidic fruits.
- Keep regular dental appointments.
- If you have bruxism, talk to your dentist about a night guard.
Prevention is always easier (and less painful) than treatment.
Everyday Tips
Correct brushing: Use a soft-bristled brush and make gentle movements, avoiding pressing hard on your teeth.
Suitable toothpaste: Choose toothpastes specifically for sensitive teeth, which contain ingredients that help relieve pain.
Dental floss: Use dental floss daily to remove plaque and food debris, preventing cavities and gingivitis.
Avoid acidic foods and drinks: Lemons, oranges, soda, and wine can increase sensitivity.
Use straws: When drinking cold or acidic drinks, use straws to reduce direct contact with your teeth.
Avoid hard foods: Nuts, popcorn, and hard foods can cause tooth fractures and increase sensitivity.
Stay hydrated: Drink plenty of water to keep your mouth hydrated and help neutralize acids.
Visit your dentist regularly: Have routine checkups to identify and treat oral problems early.
Conclusion
Tooth sensitivity can be uncomfortable, but with proper care, it’s completely manageable. Adjusting your brushing habits, investing in appropriate products, and seeking dental advice are simple steps that can transform your daily routine.
If the pain persists, don’t delay your appointment: only a dentist can identify the cause and recommend the definitive treatment to restore your fear-free smile.
