I have just brought home a 2-year-old Lab, but now my 7-year-old dog keeps showing her teeth to the new dog and also tries to attack her. How can we get her to stop?

It sounds like a refresher separation is in order. Try crating your new dog,= while letting your 7-year-old have run of the house. During that time she can familiarize herself with this new dog’s presence without feeling so threatened. Your new dog will be safer as well.
Next, reverse the crating, allowing the new dog run of your house. Both dogs should become more familiar with each other during this time. When signs of aggression diminish, release both dogs but do not allow them to interact with each other unsupervised.
You didn’t mention what breed your 7-year-old is, but you can try keeping a water bottle at hand by squirting her gently in the face to break up fights. This sometimes won’t work with larger dogs, which need to be on a leash for better control until the fighting stops.
It sounds like your dogs have not established a pack order. This should occur over time, and you may need to consult a trainer or other dog behavior expert to facilitate the process. Once your dogs do settle on a pecking order, respect that to avoid creating confusion for your dogs.
