Brushing Cita's teeth is a nightmare!!

Please tell me this daily routine will become easier!! I am about to go nuts. Each night I tell Carmen come in its time to cepilla los dientes (= brush your teeth in spanish). I have no idea if I spelled that right. I speak spanglish, I dont write en espanol. I leave the spanish up to Angel most of the time ;). Anyhow, whenever she sees the toothbrush she walks away quickly saying no, no. I haved tried a normal toothbrush and an electric toothbrush. She wants nothing to do with them. I even bought an Elmo toothbrush. She is obsessed with Elmo, I'll save that story for another day. I literally have to hold her down to get her teeth clean. Its a battle, and every time she screams and cries. I am at my wits end with brushing her teeth. Someone please tell me this is just a phase because we have been dealing with this for months. Oh and I try to let her do it herself and she just sucks the toddler training toothpaste off then tosses the toothbrush and is on her way... I feel so bad like I am making this a traumatic experience for her. I am scared that I am making her associate negativity with brushing teeth. Am I over thinking this people? Any Advice fellow parents? My current strategy that goes somewhat smoothly, is... I wet a baby washcloth and put a dab of toothpaste on one corner and swipe it across her teeth inside and out top and bottom. Then I use the other corner without toothpaste to wipe her teeth free from the toothpaste. She is much more tolerant to this latter system, but I have to be careful because she bites.... yikes!!!
