Tooth pain can be one of the most frustrating and persistent types of discomfort to deal with. When the pain occurs under a dental crown, it can be especially confusing and concerning. If you’ve ever experienced tooth pain under crown comes and goes, you’re not alone. Many people encounter this issue at some point after receiving a dental crown. This article will explore the possible causes of intermittent tooth pain under a crown and provide helpful information about how to address it.
What Is a Dental Crown?
A dental crown is a cap placed over a tooth that has been damaged, weakened, or previously treated with a root canal. Crowns are used to restore the tooth’s shape, size, and strength, and they help improve the tooth’s appearance. Crowns are made from a variety of materials, including porcelain, metal, or a combination of both, and they can last for many years with proper care.
Despite their durability, however, it’s not uncommon for people to experience some form of discomfort or pain under their crowns. This can be a source of worry, especially when the pain comes and goes.
Causes of Tooth Pain Under Crown Comes and Goes
There are several potential reasons for experiencing tooth pain under crown comes and goes, and understanding these causes can help you determine the best course of action.
1. Sensitivity to Temperature or Pressure
One of the most common reasons for intermittent tooth pain under a crown is sensitivity to hot or cold foods and drinks. When the crown is placed, the tooth underneath may still have some degree of sensitivity. In some cases, the crown may not fully seal the tooth, leading to increased sensitivity when exposed to temperature changes. The pain may come and go depending on whether or not the tooth is exposed to a hot or cold stimulus.
2. Gum Irritation or Infection
Sometimes, pain under the crown can be caused by irritation or infection of the gum tissue surrounding the crown. If the gum tissue becomes inflamed or infected, it can cause intermittent pain. This pain may worsen when you eat or drink certain foods. If the infection is not addressed, it could lead to more serious complications, such as an abscess or the need for a root canal.
3. Crown Fit Issues
If the dental crown doesn’t fit properly, it can cause uneven pressure on the underlying tooth, leading to discomfort or pain. If the crown is too high or doesn’t sit properly, it can cause a misalignment that leads to occasional pain. Over time, the crown may shift, causing pain that comes and goes.
4. Cracked or Damaged Tooth Under the Crown
In some cases, the tooth under the crown may be cracked or damaged. While the crown itself may protect the tooth, a cracked or weakened tooth can still cause discomfort or pain that flares up intermittently. The pain may come and go depending on the level of damage and the pressure placed on the tooth.
5. Nerve Irritation or Inflammation
If the tooth under the crown has had a root canal, it’s possible that the nerve inside the tooth remains irritated or inflamed. This can result in occasional flare-ups of pain, especially when the tooth is exposed to pressure or temperature changes. In some cases, a previous root canal treatment may not have fully resolved the issue, leading to ongoing discomfort.
6. Cavity or Decay Under the Crown
Although crowns are designed to protect the underlying tooth from decay, it’s still possible for bacteria to enter around the edges of the crown, leading to tooth decay underneath. If a cavity forms under the crown, it may cause intermittent pain, especially when eating or drinking. This pain can be sharp and brief but may return periodically.
7. Bruxism (Teeth Grinding)
People who grind their teeth, a condition known as bruxism, may experience tooth pain under crown comes and goes. Teeth grinding puts excessive pressure on the crown and the underlying tooth, causing irritation and inflammation. The pain caused by bruxism can be intermittent and may worsen after a night of grinding.
When to See a Dentist
If you’re experiencing tooth pain under crown comes and goes, it’s important to visit your dentist to determine the underlying cause. A dentist will perform a thorough examination, possibly including X-rays, to identify whether the issue is related to the crown itself, the tooth underneath, or other factors. Ignoring the pain or attempting to self-diagnose could lead to more serious dental issues down the road.
How to Relieve Tooth Pain Under a Crown
While waiting for your dental appointment, there are several ways you can alleviate the discomfort:
-
Use Sensitivity Toothpaste: Toothpaste designed for sensitive teeth can help reduce discomfort caused by temperature sensitivity.
-
Avoid Extreme Temperatures: If hot or cold foods and drinks are triggering the pain, try to avoid them until you can see your dentist.
-
Pain Relievers: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage pain until you receive professional care.
-
Salt Water Rinse: Rinsing your mouth with warm salt water can help reduce gum irritation and inflammation around the crown.
-
Cold Compress: Applying a cold compress to the outside of your face near the affected area can help reduce swelling and alleviate pain.
FAQs About Tooth Pain Under Crown Comes and Goes
1. Why does my tooth hurt only under the crown and not on the rest of my teeth?
Pain under a crown is typically related to issues with the tooth that was treated, the crown itself, or surrounding tissues. If the pain is localized under the crown, it could indicate that there’s an issue with the fit, the tooth beneath the crown, or a condition like gum irritation or tooth decay.
2. Can tooth pain under a crown be a sign of an infection?
Yes, tooth pain under a crown can sometimes be a sign of an infection, especially if the pain is accompanied by swelling, tenderness, or pus. If left untreated, an infection could spread and lead to more serious issues like an abscess or the need for a root canal.
3. How long will the pain last if it is caused by a temporary issue like sensitivity?
If the pain is due to temporary sensitivity, it may subside within a few days to a week. However, if the pain persists or worsens, it’s important to consult your dentist to rule out any underlying issues that may require treatment.
Conclusion
Tooth pain under crown comes and goes is a common issue that many people experience after receiving a dental crown. The pain can be caused by a variety of factors, such as sensitivity, improper fit, nerve irritation, or decay. Understanding the possible causes of this discomfort can help you determine the best course of action. If you’re experiencing persistent or recurring pain, it’s important to seek professional dental care to ensure your crown and tooth are properly treated and functioning.
