Why Your Tooth Hurts with Cold or Hot Drinks

Dental sensitivity to cold or hot foods and beverages is extremely common, though it affects some people more than others. Aside from a normal level of tooth sensitivity related to age, wear-and-tear, and other obvious causes, more significant or worsening temperature sensitivity may be related to a surprising source: a crack in your tooth, which, in some cases, you may not even know is there. 

When a tooth is cracked, the root, pulp, or other internal tissues and structures can become exposed, inflamed, or even infected, which may lead to increased sensitivity and discomfort. At Purchase Endodontics, our caring team of endodontists in Paducah, KY is highly experienced in the complexities of treating dental sensitivity caused by structural issues, like dental fractures, cracks, and more. Here, you’ll find more information about potential reasons your teeth are more sensitive than usual and what treatment options are available for a cracked tooth, should that be the culprit. 

What’s a normal level of tooth sensitivity to hot and cold? 

Mild, occasional sensitivity to hot or cold foods can be normal, especially if it’s brief and goes away quickly. This can happen as enamel naturally wears down over time or if gums recede slightly, exposing more sensitive areas of the tooth. What tends to raise concern is sensitivity that lingers, worsens, or starts to interfere with everyday habits, like drinking coffee or cold water. When sensitivity becomes more noticeable or persistent, it may point to something deeper than typical wear and tear. 

Only one tooth is sensitive — what could that mean? 

When sensitivity is isolated to a single tooth, it often suggests a localized issue rather than a general condition affecting your entire mouth. This is one of the more common signs that something structural may be going on with that specific tooth. Possible reasons one tooth is sensitive to hot or cold can include:  

• A fractured or cracked tooth 
• Early decay 
• A failing filling or restoration 
• Exposed root surfaces 
• Inflammation inside the tooth 

Because these issues can progress if left untreated, identifying the cause early can help prevent more advanced problems. 

Can you have a cracked tooth without knowing it? 

It is possible to have a cracked tooth without realizing it. Some cracks are too small to see and may not cause constant symptoms, especially in the early stages. Instead, patients often notice symptoms of a cracked tooth, like occasional discomfort when biting down or sensitivity to temperature that seems to come and go. Over time, as the crack worsens or affects deeper layers of the tooth, symptoms may become more frequent or intense. 

How are cracked teeth treated? 

Treatment for a cracked tooth depends on how deep the crack extends and whether the inner pulp of the tooth has been affected. In cases where the pulp is inflamed or infected, endodontic treatment is often recommended to remove the damaged tissue and protect the remaining structure of the tooth. This may involve procedures, such as:  

• Root canal therapy or endodontic retreatment 
• Pulpotomy or pulpectomy 
• Placement of a protective crown 

After a thorough exam, which may include imaging and other diagnostic steps, our knowledgeable team will determine which course of action may be most appropriate and effective for you. 

Will my tooth be numb after endodontic treatment for a cracked tooth? 

After endodontic treatment, the tooth will no longer have the same internal nerve response, which means it will not feel temperature in the same way it did before. However, this does not mean the tooth becomes nonfunctional. The surrounding structures, including the gums and supporting bone, still provide sensation, allowing you to bite and chew normally. Many patients find that once the source of irritation or infection is treated, the pain they were experiencing resolves and the tooth feels comfortable again — giving them back the comfort, function, and confidence they deserve.
