First, determine the cause of your dog’s loose teeth. If it is a puppy, it may be caused by tooth replacement; if it is an adult dog, it may be caused by periodontitis or dental calculus; in older dogs, it may be a manifestation of natural aging.

For loose teeth caused by dental calculus or periodontitis, you need to brush your dog's teeth regularly to keep the oral cavity clean. If necessary, you can go to the hospital for teeth cleaning or surgery. If your dog is deficient in calcium, it can also cause loose teeth. Therefore, calcium-rich foods such as bone broth, egg shells, etc. should be appropriately added to the daily diet, or supplements such as calcium tablets should be used.
