After crown preparation. The natural tooth will stay slightly irritated. For a short time. This is because the tooth has been shaped. Cleaned. Dried. Scanned. Or moulded. Then covered. The gum around the crown will feel tender for a few days.
This type of sensitivity after dental crown placement. It will improve gradually. During this time. Avoid very cold drinks. Hard foods. Also aggressive brushing around the crown.
A high bite is one of the most common reasons for crown pain when biting down. Even a tiny extra height. This will place too much pressure on the crowned tooth. So the tooth becomes sore. Because it takes more force. Than the surrounding teeth.
You will notice pain only when chewing. Tapping the teeth together. Or eating something firm. This is often a simple fix. Your dentist will check the bite with marking paper. Also polish the crown slightly. So the pressure becomes balanced again.
Sometimes the gum moves down. Also exposes a small part of the tooth root. Since root surfaces are sensitive than enamel. Cold air. Drinks. Also brushing will trigger discomfort. This will happen due to gum disease. Ageing. Hard brushing. Or poor oral hygiene around the crown.
Good brushing technique. Soft toothbrush use. Fluoride treatment. Also professional cleaning will help. But if recession is advanced. The dentist will suggest specific gum treatment.
When the original tooth has deep decay. A large filling. A crack. Or previous trauma. The nerve inside will already be stressed. Placing a crown protects the tooth. But it does not always reverse nerve inflammation.
A warning sign will be pain. That lingers after hot or cold drinks. Spontaneous throbbing pain at night. This suggests deeper nerve trouble. The tooth will need root canal treatment in such cases. Before a final long-term solution.
A crown itself will not decay. But the natural tooth underneath can. When the crown margin has a gap. Or when plaque collects near the gum line. Bacteria will enter. Then create decay under the crown.
Signs will include bad taste. Food trapping. Gum bleeding. Sensitivity. Or pain. So regular check-ups will be important. Early decay will sometimes be repaired. But deeper decay will require crown replacement.
A crown will protect a cracked tooth. But some cracks will continue deeper into the root. This will cause sharp pain when biting. Particularly when releasing pressure after chewing.
Cracked tooth symptoms will be tricky. Because the pain will come and go. A dentist will use bite tests. X-rays. Magnification. Or other checks to find the problem. Treatment will depend on how deep the crack goes.
People grind their teeth during sleep. Without knowing it. This pressure will make a crowned tooth sensitive over time. It can chip porcelain. Loosen crowns. Also strain jaw muscles.
When you wake with jaw tightness. Headaches. Or sore teeth. Bruxism will be the reason. A custom night guard will protect the crown. Also reduce pressure while sleeping. Get details on Dental Implants in Dubai.
Mild sensitivity will often be managed. For a short time. Particularly when the crown is new.
Try these steps:
Home care can be for mild symptoms. When pain continues. A dental visit will be the safer option.
