What Causes Teeth to Feel Soft? Proper Brushing Technique and Care Tips

What Does It Mean to Have "Soft" Teeth?

Some people report that their teeth feel "soft." This unusual sensation is most frequently caused by early tooth decay, but other dental issues can also cause your teeth to feel less firm and solid. Understanding the potential reasons for soft tooth sensation can help you get the right treatment to restore your dental health.

Early Tooth Decay

One of the most common explanations for perceiving that your teeth have become soft is tooth decay in its early stages. Tooth decay occurs when plaque - a sticky film of bacteria and food particles - builds up on your teeth. The bacteria in plaque feed on sugar and carbohydrates to produce acids that can erode tooth enamel.

In the earliest phase of tooth decay, these acids cause microscopic holes in the enamel called demineralization. At this stage, the process is often reversible through brushing, fluoride exposure, and reducing sugary foods. You may notice your teeth feel slightly softer as the enamel loses some mineral content.

But as the decay progresses due to frequent acid attacks, it will reach the second layer of your teeth - the dentin. Since dentin contains more organic materials, it is softer than the enamel layer. Extensive decay into the dentin will clearly make your teeth feel less solid. This stage of decay requires professional dental treatment.

Dental Erosion

Dental erosion also removes minerals from your enamel through acid exposure. But instead of coming from bacteria in your mouth, erosion acids come from external sources like:

• Acidic foods and drinks - Soda, sports drinks, citrus fruits, pickles, etc.
• Stomach acids from vomiting, reflux, or eating disorders
• Environmental exposures - Swimming in chemically treated water

This mineral loss causes teeth to feel softer and smoother. Erosion also makes teeth look more transparent and increases sensitivity. Reducing your exposure to acidic substances can help prevent further erosion.

Gum Disease

Periodontal or gum disease leads to inflammation and destruction of the tissues supporting your teeth. As the gums recede due to periodontitis, more of the tooth root becomes exposed.

Tooth roots are covered with a thin layer of cementum rather than hard enamel. This softer cementum layer is more prone to decay, so your teeth may feel less solid as the roots become exposed and vulnerable to cavities.

Tooth Grinding and Clenching

Excessive grinding or clenching of your teeth, known as bruxism, can alter the texture and sensation of your teeth over time. Because this habit applies heavy forces against your teeth, you eventually lose some of the enamel layer.

Thinner enamel causes your teeth to feel softer and appear more transparent. It also make them more sensitive and prone to decay. Using a night guard helps prevent the grinding motions from damaging your tooth surfaces.

Proper Tooth Brushing Technique

If your teeth feel soft or sensitive, it's important to avoid brushing too aggressively. Scrubbing hard in an attempt to clean your teeth better can actually do more harm than good.

Use a Soft-Bristled Toothbrush

Dentists recommend using a toothbrush with soft, rounded nylon bristles. The stiff bristles of medium and hard toothbrushes can damage tooth enamel, dentin, and even your gums. Look for toothbrushes labeled “soft” from brands like Oral-B, Colgate, and Sensodyne.

Brush Gently

Apply light pressure as you brush using short, gentle strokes. Let the bristles do the work rather than forcibly scrubbing your teeth. Concentrate on ensuring you clean all tooth surfaces instead of brushing aggressively.

Don't Brush Right After Eating

Brushing too soon after eating or drinking acidic foods or beverages can increase enamel erosion. Acids soften the enamel, making it more prone to abrasion from brushing. Wait at least 30-60 minutes after eating before brushing.

Bristles Should Be Angled Into the Gumline

Position the head of your toothbrush at a 45-degree angle against your gums. Gentle jiggling motions will allow the bristles to slide below the gumline to remove plaque and debris. Take care not to forcefully jam the bristles into your gums.

Brush For 2 Minutes

Set a timer or play a song you know lasts 2 minutes to ensure you brush for the full recommended time. Rushing through may leave plaque behind, while brushing longer tends to damage enamel and irritate gums.

Additional Tips for Sensitive Teeth

Making some small tweaks to your oral hygiene routine can help alleviate tooth sensitivity when your teeth feel soft or weak:

• Use sensitivity toothpaste - Formulas for sensitive teeth contain ingredients like potassium salts to numb pain.
• Rinse with fluoride mouthwash - Fluoride strengthens enamel to reduce sensitivity.
• Avoid whitening products - Bleaching agents in whitening strips or gels can irritate the dentin.
• Drink cold liquids through a straw - This reduces contact between drinks and your enamel.
• Get dental bonding if needed - Bonding agents can protect exposed roots.

Be sure to see your dentist regularly for exams and cleanings. Professional scaling can remove acidic plaque from below the gumline. Your dentist can also check for cavities or dental erosion and help strengthen weakened areas with sealants or fillings.
