Excess blood flow in pulp

Excess blood flow to the pulp gives rise to hyperaemia. This is a result of gingival recession causing exposure of the root of the tooth and dissolved cementum. The pulp consists of blood vessels and nerve tissue, which when inflamed due to bacterial infection causes pulpitis. The excess blood flow cause widening of blood vessels that is vasodilatation. Which may also leads to the tooth pain in future but without clinical signs of cavity. 

If there is no sign of a cavity, yet there is tremendous tooth pain, then there are chances you may need to visit your dentist. A sinus infection, is a less common but significant cause of toothache.

Dental problems are never any fun, but the good news is that most of them can be prevented even toothache with no signs of cavity.

Hyperaemia toothache

The tooth in general is sensitive to heat and cold due to increased amount of blood flow. It is also sensitive too sweet food. Such teeth show no clinical caries when examined. Hyperaemic tooth shows two types of changes in the pulp;

Reversible pulpitis is of mild nature. The inflammation in such cases mild and the tooth saved as the pulp remains healthy. In reversible pulpitis, the pain disappears after seconds. The pulp able to heal when the irritation factor removed. This not seen in case of irreversible pulpitis. 

Irreversible pulpitis causes severe pain wherein the pulp cannot be saved and the tooth goes into a root canal treatment or if delayed further then an extraction of that tooth. The pulp is surrounded by dentin. Therefore, there is no way for the pressure created to dissipate, the increased blood flow will result in pain. 

The causes of Hyperaemia could be: 

Intentional crown preparation done to a healthy tooth, which acts as an abutment. 

Trauma to the tooth which may lead to thin fracture in enamel. 

Deep scaling procedures affecting to the root. 

Root caries in close proximity to the pulp. 

Orthodontic wires create pressure to teeth causing blood flow changes.
