Tooth pain after filling
Sometimes, tooth filling is not the end of your tooth problems and you still feel pain weeks and months after the filling. So in this article, we will get to know if it is normal to feel throbbing pain when you drink something cold or when chewing, and we will advise you with some home remedies to relief the pain after a dental filling.
Tooth filling is indicated to replace a missing part of the tooth, due to decay or fracture. It can be made out of composite, silver amalgam, gold or porcelain. Depending on the location, extent, diagnosis of the decay, your dentist will choose the appropriate filling for your case.
what causes tooth pain after fillings?
The pain on your teeth comes from 2 origins;
-The dental pulp: is a soft tissue inside of the tooth, it contains nerves, blood vessels, and connective tissues. It is responsible for the sensitivity of cold and hot on the tooth. When the pulp of the tooth is exposed because of decay or fracture, the pulp becomes very sensitive to temperature changes, which causes throbbing pain.
-The alveolar bone: The alveolar bone contains nerves that can cause pain as well. After necrosis in the root of the tooth due to untreated deep decay, fracture, or inappropriate root canal treatment, pus and inflammatory tissues form at the end of the root of the tooth. This results in pressure on the nerves of the alveolar bone, which can be very painful.
Why do I have teeth pain after filling?
Teeth sensitivity after filling can be because of different reasons depending on the diagnosis of the tooth before the filling and depending on the filling itself.
The filling should restore the tooth in a way that it lines up with the other teeth when biting or chewing. If it is too high, the filled tooth will receive most of the bite pressure when chewing and therefore will become more sensitive.
Pulp nerve irritation:
The pulp of the tooth contains the sensitive nerves that are responsible for the pain. After your dentist removes the decay and puts the filling material. If it is too close to the nerves, it often causes tooth pain after the filling. Some filling materials like composite release heat when polymerizing, which can also cause toothache for a few days after the filling.
After a pulp capping:
Pulp capping is used as a technique to save the vitality of the tooth by preventing the dental pulp from necrosis, after being exposed, or nearly exposed during a cavity preparation or trauma. The dentist applies a filling material directly on the pulp, and this procedure can sometimes cause sensitivity and pain after tooth filling. The toothache usually disappears after a few days or weeks, but if it stays for longer, this might mean that your pulp is inflamed and has a reversible or irreversible pulpitis that needs medication and a root canal treatment.
Cracked/ loose tooth fillings:
Tooth fillings often crack after a period of time, the crack line makes the dentine and pulp of the tooth exposed which causes you toothache. If your tooth filling is old, then it is time to replace it, if it is very new, maybe the tooth was too weak to support the filling material.
Composite fillings can crack if they interact with fluids before your dentist finished the light curing, which is why your dentist tells you to keep your mouth open.
Dental filling material allergy:
Some people have allergic reactions to different dental filling materials and especially silver amalgam, the allergy can be a skin rash or itching, the least allergic dental filling material is gold.
Root canal treatment related pain:
Even if you had a root canal treatment, your tooth might still hurt because of different reasons:
– periodontal ligament irritation: when the dentist prepares and fills the root canals, the periodontal ligament might be irritated and cause you pain after filling, the pain is normal in the first 2 to 3 weeks, and periodontal ligament often heals with time.
-Overfilling: an overfilling occurs when the root filling materials exceeds the root and reaches the alveolar bone, if the overfilling is less than 1mm, it often heals with time.
-peri-apical abscess: due to bacteria and necrotic tissues, alveolar bone irritation, pus can develop at the tip of the root.
This type of abscess accrues:
• Months after the filling
• If the canals are not well disinfected
• A missed root canal that is not treated
• Over filling
Types of tooth pain after filling
Throbbing tooth pain after filling:
This pain typically occurs after drinking or eating cold, hot or sweet food. This means that your tooth nerves are irritated and this can happen for numerous reasons:
• Tooth filling is very close to the dental pulp
• Irritated pulp because of the exothermic heat released during polymerization of a light curing composite resin.
• Residual or recurrent caries.
• An overdrying of the tooth by the dentist before filling
• Dental filling material allergy
• Incorrect bite line of the filling
• Cracked filling
Tooth pain after filling when chewing:
This pain is explained as following: when you chew, you apply pressure on the periodontal tissues and the alveolar bone at the tip of the dental roots. If these tissues are irritated, it will cause you pain when chewing.
Some of the reasons for the alveolar bone irritations are:
• Reversible periodontal ligament irritation
• Necrotic pulp
• Peri-apical abscess
• Incorrect bite line of the filling
• Overfilling of the root canals
• Missed root canals
• Residual bacteria
• Tooth fracture
How long should a tooth hurt after filling?
Tooth pain after filling can be normal in the first one or two weeks after the treatment, because your body needs to adapt to the new filling material and it needs time to heal. However, if pain after filling a tooth lasts for more than one month, it is probably alarming and you need to visit your dentist so that he will diagnose the problem and treat before it is too late.
If your dental pulp is irritated and not treated on time, it can cause necrosis and abscess.

• Using an over-the-counter anti-inflammatory, like ibuprofen or acetaminophen. It is a great remedy to relief the pain. It is better to consult your dentist before, if you have any allergies to medication .
• Avoid common sensitive teeth triggers (hot, cold, sweet, acid foods): these types of food trigger tooth pain after filling and it is advised to avoid them temporarily.
• Gently brush and floss your teeth regularly to remove the food leftovers that stick and cause pain.
• Using a desensitizing toothpaste is a good remedy to reduce sensitivity after a tooth filling.
• Topical numbing ointment: it can reduce toothache instantly and relief pain.
