Yes, bitten nails can grow back to normal, but the extent of recovery depends on the severity and duration of the nail biting habit.
Occasional vs. Habitual Nail Biting
-
Occasional nail biting: If you bite your nails occasionally, they will likely grow back normally. The damage is minimal, and the nail bed remains unaffected. ([Source 1, Source 3])
-
Habitual nail biting: Chronic or habitual nail biting, however, can cause irreversible damage to the nail bed. This damage may result in nails growing back with a different shape or other deformities. ([Source 1, Source 3, Source 5, Source 6]) The nail may grow back longer, but might never fully regain its original shape or length. ([Source 4]) It can take several months (3-6 months) for noticeable regrowth, depending on the extent of the damage. ([Source 10]) Even after stopping, it can take time for the nail beds to return to their full length. ([Source 2, Source 7])
Factors Affecting Nail Regrowth
Several factors influence how well bitten nails grow back:
- Severity of damage: The more severe the damage to the nail and nail bed, the longer and more challenging the recovery process will be.
- Duration of habit: Years of nail biting can lead to more significant changes in nail shape and growth.
- Nail care: Proper nail care, including hydration and gentle cuticle pushing, can promote healthy nail growth. ([Source 9, Source 11])
Conclusion
While bitten nails can regrow, complete restoration to their pre-biting state isn't guaranteed, particularly in cases of long-term or severe nail biting. The regrowth process may take several months and might result in some lasting changes in nail shape and appearance.
