  "textContent": "With age, teeth get increasingly brittle and susceptible to damage from tooth decay, which can eventually lead to tooth loss. Teeth have an intrinsic capability to regenerate, a process that is driven by dental pulp stem cells (DPSCs) that replenish the dental pulp, including the dentin-producing cells called odontoblasts.",
