Due to the numbing agent applied during the dental filling procedure, you might not feel any sensation around the operated area until after a few hours. When this wears off, you might experience some sensitivity around the area. These sensations might include:
A number of reasons can contribute to why you feel these sensations after a dental filling. It is worthy of note that although it is normal for teeth to hurt after fillings, we recommend you consult your Orthodontics if you experience prolonged sensitivity and discomfort.
In some cases, a filled tooth can be taller than the surrounding teeth. This will lead to an uneven surface and a change in your bite.
In turn, you will experience increased pressure on the affected tooth and discomfort when you bite or clench your teeth. If you notice this, we recommend you contact your Orthodontics immediately, as an uneven bite can crack the filling.
As mentioned earlier, fillings can be done with certain materials. If you are allergic to some of these materials, you might experience discomfort around the affected area. That is why consulting with your Orthodontics is important before you carry out any dental procedure. It ensures that the right materials are selected based on your needs and dental history.
Your pulp is the connective tissue that forms the centre of your teeth. Pulpitis refers to the inflammation of the pulp, which is rare after tooth filling. It might occur if the tooth has experienced trauma, maybe because of an accident, a cracked tooth, or a blow.
Another reason for pulpitis is if the tooth has decayed to the inner pulp layer, therefore introducing bacteria into this sensitive area.
There are two types of pulpitis:
1. Reversible Pulpitis: In this case, the pulp remains healthy, and the mild inflammation will heal independently.
2. Irreversible Pulpitis: Here, the pulp becomes damaged and begins to die. In this case, you will need to undergo a root canal treatment to save your tooth.
As always, consult your orthodontist to ascertain the level of pulpitis truly. Depending on the severity, a restorative procedure can resolve pulpitis.
You might experience pain in the affected tooth after a filling, particularly a deep filling, because of irritation of the nerves. A deep filling occurs when the dentist has to remove decaying material and fill very close to the nerve endings at the root of the tooth.
Usually, the enamel and cementum protect this area from exposure. When deep filling occurs, the nerves might get irritated and inflamed, causing discomfort. This usually heals on its own over time.
