Good Teeth vs Bad Teeth – 10 Key Differences 

Following are some of the key differences between healthy and diseased teeth. 

1- Coloration

Normal or healthy teeth have a tooth color varying between white and off-white without any patches of differently colored.

In contrast, unhealthy teeth often appear yellow or brownish and may have visible cavities.

2- Integrity

Good dental health is completely normal, without any visible cracks or chips. In contrast, diseased teeth may appear broken, chipped, cracked, or even impacted when viewed outside.

3- Smell

Healthy teeth usually don’t have a foul smell. Teeth affected by oral diseases have a foul odor that can strike anywhere and make it an uncomfortable experience.

4- Pain

When your dental health is good, you don’t have any pain or discomfort. However, those with dental issues often complain of severe toothaches.

5- Sensitivity

Healthy dental conditions typically involve minimal sensitivity to temperature changes or sweetness. However, oral health issues have no tolerance for hot and cold temperatures or sweets.

6- Alignment

Normal and healthy dental alignment features straight alignment without gaps. In contrast, bad teeth often have alignment issues such as crowding, snaggletooth, overbite, and underbite.
