If bone loss is greater than this percentage, the tooth needs to be removed?

Explanation:
The amount of bone support remaining around a tooth governs whether it can be saved or should be removed. When bone loss reaches about three-quarters (75%) of the root length, there is so little supportive structure left that the tooth is unlikely to function well or stay infection-free, even with treatment. This 75% threshold is the practical tipping point clinicians use to decide extraction. Less than this amount leaves more potential for periodontal therapy and tooth retention, while extremely severe loss (near 90%) reinforces extraction as the appropriate step. So, the 75% figure best represents the point at which extraction becomes the recommended course.
