Common Dental Problems and How They're Typically Treated
By the Jackson Dental team ·
How a cavity forms
A cavity isn't just "sugar eating your teeth." Bacteria that live in dental plaque feed on sugars and starches left on your teeth and produce acid as a byproduct. That acid pulls minerals out of the enamel faster than saliva can put them back, a process called demineralization. Early on, fluoride and better hygiene can still reverse that process. Once it breaks through the enamel into the softer dentin underneath, the damage needs to be physically repaired: a filling for a smaller cavity, a crown for more extensive damage, or a root canal if decay has reached the nerve.
Gum disease: the timing that matters
Gum disease starts as gingivitis, inflamed, sometimes bleeding gums caused by plaque buildup along the gumline. At this stage it's fully reversible with a professional cleaning and better home care, because no permanent damage has happened yet. Left untreated, it can progress into periodontitis, where the infection has begun breaking down the bone and connective tissue that hold your teeth in place. That's the line that matters clinically: once that structural support is lost, you generally don't get all of it back, even though treatment can still manage the infection and, to some degree, rebuild what's left. It's why dentists take early gum inflammation seriously instead of waiting to see whether it clears up on its own.
Tooth sensitivity, briefly
Sensitivity to hot, cold, or sweet foods gets its own full explanation in our post on cold-weather sensitivity, but the short version is that it usually traces back to worn enamel, gum recession exposing the tooth root, or occasionally a cavity or crack. Persistent sensitivity calls for a dental exam, not just a change in toothpaste.
The pattern across all of it
Cavities and gum disease both start small, progress quietly, and get significantly more involved to treat the longer they go unaddressed. A cavity caught early is a filling; caught late, it can mean a root canal or an extraction. Gingivitis caught early is fully reversible; left alone, it can become permanent bone loss. That's the whole case for routine checkups even when nothing seems wrong: they're built around catching things at the cheap, reversible end of that timeline.
