Do Cavities Hurt?

Tooth decay or cavities often start small and painless, affecting only the tooth's outer enamel. As they progress deeper into the dentin and potentially the pulp, they can cause pain and sensitivity.

Early detection and treatment are key to preventing further damage and discomfort. Let’s discuss how to identify cavities, the treatment options available, and how to prevent them.

Why Do Some Cavities Hurt, and Others Don't?

Cavities located in less sensitive areas, such as on the biting surface or in the back of your mouth, might not cause pain until they become quite large. However, cavities on the sides of teeth, where food tends to get trapped, are often more sensitive even at earlier stages.

This is due to the tooth's structure. The outer enamel has no nerves, but the underlying dentin does. Once decay reaches the dentin, it can cause sensitivity or pain. 

In severe cases, the cavity reaches the pulp (the tooth's nerve center), leading to intense pain and inflammation.

What Does Cavity Pain Feel Like?

Cavity pain can vary in intensity and duration, depending on the extent of decay. Here's how to recognize different types of cavity pain:

• Dull and aching pain ⁠— A persistent, dull ache that may come and go often indicates that the decay has reached the dentin layer, but the nerve isn't severely inflamed yet.
• Sharp and sudden pain — Experiencing sharp, sudden pain, especially when exposed to cold, hot, or sweet stimuli, is another sign of dentin involvement. While it can indicate an earlier stage of decay, it's still important to seek treatment promptly.
• Throbbing pain — Severe, throbbing pain that is difficult to ignore is a red flag. It often suggests that the decay has reached the pulp, leading to infection and potentially causing systemic symptoms like fever or malaise. This type of pain requires immediate dental attention.

Does Sensitivity Always Mean Cavities?

Sensitivity doesn't always mean a cavity. Cavity pain usually worsens over time, especially if you don't see a dentist.

Conversely, sensitivity might flare up and then go away. It’s often caused by worn enamel, a cracked tooth, or gum recession.

Effective Treatment for Cavity Pain

Cavities can be a major source of discomfort and, if left untreated, can have a lasting impact on oral health. Fortunately, several successful dental treatments and preventive measures are available to address cavities and safeguard the health of your teeth.

Dental Fillings

One common treatment for cavities is a dental filling. During this procedure, your dentist removes the decayed part of the tooth and then fills the resulting hole with a material like composite resin or amalgam.

This restores the tooth's shape and function, halting further decay and relieving any pain caused by the cavity.

Root Canals

When decay reaches the inner part of your tooth, a root canal may be necessary. Root canals are highly effective in saving teeth, and modern techniques make the procedure relatively painless.

This procedure involves:

• Removing the infected pulp (the soft tissue inside the tooth)
• Cleaning and disinfecting the canals
• Sealing them to prevent reinfection.

Fluoride Treatment 

Fluoride is a natural mineral that strengthens tooth enamel and helps protect against cavities. If you're prone to cavities, your dentist may recommend professional fluoride treatments. 

They’ll apply a high fluoride concentration to your teeth, which can help remineralize enamel and even reverse early signs of decay.

How to Prevent Future Cavities 

Prevention is better than cure. Cavities are caused by bacteria in your mouth that feed on sugar and produce enamel-eroding acids. This can create holes in the protective enamel layer and lead to cavities.

To prevent cavities, you must maintain good oral hygiene habits. Here are our suggestions to do this:

• Brush twice a day for two minutes with fluoride toothpaste. Fluoride strengthens your enamel, making it resistant to those acids. 
• Floss to get into those tight spaces between your teeth where your brush can't reach. It removes food particles and breaks up plaque, denying those bacteria their hiding spots.
• Limit sweets since sugary snacks and drinks. Choose whole foods like fruits and vegetables more often. If you do indulge, give your mouth a good rinse with water afterward.
• Visit your dentist. Regular checkups and cleanings allow them to spot problems early and remove stubborn plaque.

Cavity pain is a warning sign from your tooth, indicating underlying decay. Prompt intervention can prevent further damage and potentially reduce the need for extensive dental procedures.

You can proactively manage dental discomfort by knowing what dental care options are available to you and adopting effective oral hygiene practices. These can help you preserve your natural teeth and ensure long-term oral well-being.
