Diabetes type 2 symptoms: Tooth decay is linked to high blood sugar levels

Type 2 diabetes can lead to tooth decay – something you may not have thought was associated with high blood sugar levels. Too much sugar in the blood can result in more sugar in the saliva, which is the perfect breeding ground for bacteria. The charity Diabetes UK explained the bacteria in the mouth then produces acid that attacks the tooth enamel and damages the gums. Blood vessels in the gums can also be targeted by the bacteria, causing infections.
The double-whammy is that gum disease and infections can then trigger even higher blood sugar levels, putting you more at risk of wider complications, such as heart disease.
Uncontrolled diabetes can lead to gum inflammation (gingivitis) and infection of the soft tissue and bones that supports the teeth (periodontitis).
There may be issues with oral thrush, a dry mouth, tooth loss or abscesses.
Early signifiers of dental issues include redness, soreness, and bad breath.
