5 Of The Most Common Causes Of Toothache
                     5 OF THE MOST COMMON 
CAUSES OF TOOTHACHE
TOOTH DECAY, DENTAL 
CAVITIES, AND CARIES
Cavities are holes that indicate permanent 
damage to the hard covering of a tooth and are 
the leading causes of toothache. They 
aggravate as they progress into the soft parts 
of the tooth, such as the pulp that contain soft 
tissue and nerves. Without treatment, they can 
cause severe infections and tooth damage.
TOOTH ABSCESS
A tooth abscess is a sac filled with pus, usually 
caused by an infection. The infection could 
result from tooth decay or chipping or breaking 
a tooth, creating an enamel opening. Bacteria 
enter the tooth’s centre or pulp through that 
opening which causes an infection. The 
infection spreads from the tooth’s root to the 
surrounding tissue, like the gum and the bones 
holding the tooth in the jaw.
BRUXISM OR TEETH 
GRINDING
Bruxism is the regular grinding of teeth, 
consciously or unconsciously, for instance, 
during sleep. It causes jaw muscle injuries and 
aches. Jaw grinding also leads to the wearing 
out of teeth and eventually to aching teeth and 
their loss.
SINUSITIS
A sinus infection can cause teeth to ache, 
especially the teeth at the upper back. Sinuses 
are empty spaces in the skull linked to the 
nasal cavity. When infected, the tissues within 
the sinuses become inflamed and cause pain 
due to the pressure.
GUM DISEASE
Gingivitis and periodontitis are gum diseases 
where the main symptom is a toothache. 
Gingivitis occurs first as a mild infection, but if 
untreated, it progresses into aggressive 
periodontitis. These gum diseases cause gum 
inflammation and the gum’s reddening at the 
base of the teeth called the gingiva. It advances 
due to the accumulation of plaque, which 
causes the infection along the gingiva.
