Yes, it is OK to have 28 teeth.
The reference states that the average mouth is made to hold only 28 teeth. The other four teeth that some people develop are wisdom teeth, which can sometimes cause problems if there isn't enough room for them.
Having 28 teeth means that you likely do not have wisdom teeth, or that they haven't erupted yet. This is perfectly normal. It is only when all 32 teeth, including wisdom teeth, try to fit into a mouth designed for 28 that issues can arise.
Here's a summary:
Number of Teeth | Status | Potential Issues |
---|---|---|
28 | Normal, Average | None expected, healthy mouth |
32 | Normal, with Wisdom Teeth | Overcrowding, impacted teeth, pain, infection |
In conclusion, 28 teeth is perfectly fine and often represents a healthy, comfortable dental arrangement.
