You wonder: is something wrong? Did the doctor do something wrong?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most probably not. <\/span><b>Pain or tenderness after a filling is common and, in most cases, completely normal.<\/b><span style=\"font-weight: 400;\"> The tooth has had an operation - even a minor one - and needs a few days to settle down.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But there are also situations where pain means something needs to be corrected. The difference is in how it hurts, how much it hurts and how long it lasts.<\/span><\/p>\n<h2><b>Is it normal to hurt after a filling?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Yes - within certain limits and for a short period.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When the doctor removes the decay and prepares the tooth, the nerve inside (along with the blood vessels that keep the tooth alive) can become slightly irritated. This happens even if the nerve has not been directly touched. This is a normal reaction of a healthy tooth to a procedure.<\/span><\/p>\n<p><b>What is normal:<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Sensitivity to cold, hot or sweet in the first 1-4 weeks<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Slight embarrassment when biting for the first few days<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mild pain that passes quickly and decreases with time<\/span><\/li>\n<\/ul>\n<p><b>What is not normal:<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pain that comes on by itself for no reason<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Severe biting pain that doesn't go away after a few days<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Sensitivity worsening instead of decreasing<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pain at night that wakes you from sleep<\/span><\/li>\n<\/ul>\n<h2><b>Causes of pain after lead filling<\/b><\/h2>\n<h3><b>1. The nerve is inflamed after surgery<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">If the cavity was deep and close to the nerve, the nerve may remain inflamed after the filling has been placed. When the inflammation is mild, it may pass on its own - without any further treatment.<\/span><\/p>\n<p><b>How you feel:<\/b><span style=\"font-weight: 400;\"> Increased sensitivity to cold or heat, which lasts more than a few seconds (maybe 10-30 seconds), but doesn't occur for no reason.<\/span><\/p>\n<p><b>What to do:<\/b><span style=\"font-weight: 400;\"> Tell your doctor how you feel. He or she may put a soothing material under the filling or watch the tooth for a few weeks. If the nerve calms down, the tooth stabilizes. If it doesn't, another treatment will be needed.<\/span><\/p>\n<h3><b>2. Plumb too high<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">One of the most common causes - and one of the easiest to solve. When you sit with your mouth open at the dentist, the muscles in your face are relaxed and the way your teeth meet when biting is slightly different to normal. The result: the filling may stick out a little higher than it should, and the tooth hits first every time you close your mouth.<\/span><\/p>\n<p><b>How you feel:<\/b><span style=\"font-weight: 400;\"> Pain or discomfort when biting on exactly that tooth. Doesn't go away on its own.<\/span><\/p>\n<p><b>What to do:<\/b><span style=\"font-weight: 400;\"> Go back to the doctor - adjusting the filling takes 5-10 minutes and fixes the problem immediately. Don't get used to the pain: leaving the filling too high can lead to chronic sensitivity or even tooth cracks.<\/span><b>Valentin: and the pain increases in intensity, it can also give headaches<\/b><\/p>\n<h3><b>3. The nerve has been too damaged and can no longer heal itself<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">If the bacteria from the decay has already reached the nerve before the doctor intervenes, the inflammation does not go away by itself. Even after the filling has been put in correctly, the nerve may continue to deteriorate.<\/span><\/p>\n<p><b>How you feel:<\/b><span style=\"font-weight: 400;\"> Pain that comes on for no reason, throbbing (like a knocking in the tooth). Sensitivity to heat that does not go away even after removing the heat source. Pain at night.<\/span><\/p>\n<p><b>What to do:<\/b><span style=\"font-weight: 400;\"> See a doctor urgently. You will need <\/span><b>root canal treatment<\/b><span style=\"font-weight: 400;\"> - the infected nerve is removed, the canals are cleaned and sealed. The tooth can be saved, but the longer you wait, the more complicated the situation becomes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u2192 Root canal treatment at Smile City, Sector 6<\/span><\/p>\n<h3><b>4. New cavities under the filling<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">If the filling hasn't completely covered the cavity or its edges haven't bonded perfectly to the tooth, bacteria can get underneath and make a new cavity. This is called <\/span><b>secondary caries<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><b>How you feel:<\/b><span style=\"font-weight: 400;\"> Sensitivity that appears or worsens months or years after you put the filling in. Sometimes an unpleasant taste.<\/span><\/p>\n<p><b>What to do:<\/b><span style=\"font-weight: 400;\"> Go for a check-up. The doctor can see secondary caries with the naked eye or on X-ray. The filling should be replaced and the decay treated. The earlier you spot it, the easier the treatment.<\/span><\/p>\n<h3><b>5. Cracked or fractured tooth<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A tooth with a large filling can sometimes develop a small crack - especially if you grind your teeth at night or bite hard objects. Cracks are hard to see and can cause intermittent pain.<\/span><\/p>\n<p><b>How you feel:<\/b><span style=\"font-weight: 400;\"> A sharp pain, like a sharp pain, when biting or releasing pressure. Sometimes it's hard to tell exactly which tooth it's coming from.<\/span><\/p>\n<p><b>What to do:<\/b><span style=\"font-weight: 400;\"> Go to the doctor. He can detect the crack with special instruments or dyes. Treatment depends on the severity - it may be a dental crown or, in severe cases, tooth extraction.<\/span><\/p>\n<h3><b>6. Reaction to lead material<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Rarely, some patients are sensitive to certain filling materials - usually old metal fillings (amalgam), less often white fillings (composite) or the adhesives used to fix the filling.<\/span><\/p>\n<p><b>How you feel:<\/b><span style=\"font-weight: 400;\"> Generalized sensitivity without a specific cause.<\/span><\/p>\n<p><b>What to do:<\/b><span style=\"font-weight: 400;\"> Tell the doctor.

If it feels like you're \u201ebumping\u201d into it with each bite, or if chewing only bothers you on that side - the filling is probably too high.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Don't get used to it.

That's why many people don't feel anything until the decay gets close to the nerve.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Dental intervention, although necessary, is a direct touch to the tooth. Even if the nerve has not been touched, it may be slightly irritated by the vibrations of the drill, the temperature difference or the materials used. This reaction is temporary and is part of normal recovery.<\/span><\/p>\n<h2><b>Conclusion<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Pain or tenderness after a filling is, in most cases, normal and temporary.
