What to Drink (and Avoid) When You Have a Toothache

A toothache is a sudden, intense pain in or around a tooth, often signaling a dental problem. This discomfort usually results from inflammation or irritation of the nerve-containing pulp deep inside the tooth. Irritation is frequently a consequence of advanced dental decay, physical trauma, or an underlying infection. While awaiting professional dental care, managing beverage choices is a practical, temporary step to minimize pain and prevent further irritation.

Beverages That Provide Immediate Comfort

The most effective beverages for managing tooth pain are those with a neutral pH and a moderate temperature. Plain, room-temperature water is the safest choice, providing necessary hydration without introducing irritating compounds or triggering sensitivity. Sipping water slowly also helps rinse away food particles and bacteria without disturbing the affected area.

Mild, non-acidic herbal teas, such as chamomile or peppermint, offer temporary soothing effects when consumed lukewarm. Peppermint contains menthol, which provides a mild, cooling sensation and temporary numbing effect on irritated tissue. Chamomile is known for its gentle anti-inflammatory properties, which may help calm swollen gums.

The temperature is crucial, as extreme heat or cold can worsen the pain. Consuming mild liquids at a temperature close to the body’s internal temperature ensures the least thermal shock to the tooth. Gently sip these beverages and avoid swishing them forcefully over the painful area.

The Essential Drinks to Avoid

When experiencing a toothache, eliminate highly acidic and sugary drinks, as their chemical composition directly aggravates the underlying issue. Highly acidic beverages, including carbonated soft drinks, sports drinks, and citrus juices, are major culprits. The low pH causes acid erosion, rapidly wearing down exposed dentin and enamel, and directly exposing nerve endings.

This chemical attack intensifies existing pain by increasing tooth sensitivity. Sugar-sweetened drinks, such as fruit juices and sweetened teas, present a second problem. Bacteria feed on the sugar, rapidly producing acid as a metabolic byproduct, which accelerates decay and increases inflammation within the tooth pulp.

Even sugar-free carbonated beverages should be avoided, as the carbonation itself introduces acidity that irritates exposed dental tissues. Consuming these liquids will prolong discomfort and potentially worsen the condition before treatment.

Why Extreme Temperatures Intensify Tooth Pain

Extreme temperatures, whether from hot coffee or ice water, intensify tooth pain through the hydrodynamic theory. A healthy tooth is protected by enamel, beneath which lies the dentin. Dentin contains thousands of microscopic channels, called dentinal tubules, filled with fluid that lead directly to the sensitive inner pulp and nerve.

When enamel is compromised by decay or trauma, these dentinal tubules become exposed. Applying extreme heat or cold causes the fluid within these tubules to move rapidly. This swift movement creates pressure changes, which are transmitted to the nerve endings in the pulp.

The resulting pressure change is interpreted by the nerve as a sharp, intense jolt of pain. Cold stimuli cause the fluid to flow away from the pulp, while heat causes it to flow toward the pulp; both movements trigger the painful nerve response.

When to Seek Professional Help

While beverage adjustments offer temporary relief, they do not address the root cause of a toothache, which requires professional intervention. Any tooth pain that is persistent, severe, or lasts longer than 24 hours warrants an immediate consultation with a dentist. The pain signals that the underlying problem, such as an infection or decay, is progressing.

Signs indicating an urgent situation include swelling in the face or jaw, a fever, or difficulty swallowing or breathing. These symptoms may signal a spreading dental abscess, a serious infection that can quickly become life-threatening. Prompt dental diagnosis and treatment are necessary to prevent serious health complications; do not rely on home remedies when these indicators are present.
