Start offering an open cup or free-flow cup at around six months, aim to stop bottles completely between 12 and 18 months, and never put a child to bed with a bottle containing anything other than water. A short period of spilling, fussing, and reduced intake during the switch is completely normal and temporary. What is not normal is prolonged bottle use into the toddler years, because it is strongly linked to early childhood caries and to bite changes that a Concord dentist will often spot before parents do.
The bottle itself is not the enemy. Duration and contents are. A bottle finished in ten minutes at a mealtime behaves very differently from one carried around all afternoon.
Extended bottle feeding with milk or juice is the single most common cause of decay on the upper front teeth in toddlers, and severe cases can require paediatric dental crowns to save the tooth.
In advanced cases where the tooth cannot be restored, dental extraction becomes necessary, and losing a front baby tooth early affects speech and spacing.
If a child has sudden pain, a visible abscess, or facial swelling, that requires emergency dental treatment the same day rather than a routine appointment.
Cost is rarely a reason to delay, since CDCP dental services cover eligible children for preventive and restorative care.

Why the Transition Matters
Dental Reasons
- Early childhood caries. Prolonged contact between the teat and the upper front teeth, combined with sugars in milk or juice, produces the characteristic decay pattern along the gum line.
- Reduced saliva at night. Salivary flow drops during sleep, so a bedtime bottle leaves sugar pooled against the teeth for hours.
- Bite development. Extended sucking on a teat can contribute to an anterior open bite and narrowing of the upper arch.
- Tongue posture. Cup drinking encourages a mature swallow pattern, while prolonged teat use maintains an infantile pattern.
Nutritional and Developmental Reasons
- Excess milk intake from a bottle can displace iron-rich solid foods and contribute to iron deficiency.
- Cup drinking supports oral motor development, lip closure, and speech readiness.
- Independence and self-feeding skills develop earlier with cups.
- Ear infections have been associated with feeding in a fully reclined position.
The Right Timeline
- 6 months. Introduce a small open cup or free-flow beaker with water at mealtimes. Expect spills. This is practice, not replacement.
- 9 months. Offer some feeds from a cup. Most babies can manage sips reliably by now.
- 12 months. Begin actively phasing bottles out. This is the target age recommended by most paediatric and dental bodies.
- 15 months. Bottles should ideally be gone. Milk is served in a cup at meals.
- 18 months. Bottle use beyond this point warrants a conversation with your dentist or physician.
- Any age. Never a bottle in bed with anything other than plain water.
Choosing the Right Cup
- Open cup: best for oral development and the ultimate goal. Messy at first but children adapt quickly.
- Free-flow beaker without a valve: recommended by dental professionals because it does not require sucking and empties quickly.
- Straw cup: a good option that encourages lip closure and mature tongue position, provided the drink is not carried around all day.
- 360 degree rim cup: reduces spills while still requiring a sipping action rather than sucking.
- Non-spill valved sippy cup: the least ideal option. The valve forces a sucking action almost identical to a bottle and encourages all-day sipping. Useful for car journeys but not as a primary cup.
Step by Step: A Practical Transition Plan
- Pick a calm week. Avoid starting during illness, teething, travel, or a new sibling arrival.
- Replace the least important feed first. Usually the midday bottle. Offer milk in a cup at that meal instead.
- Wait three to five days before removing the next one. Gradual change reduces resistance.
- Save the bedtime bottle for last. It is the most emotionally attached feed and the most damaging one dentally.
- Dilute if needed. Some parents progressively water down bottle contents while offering full milk in the cup, making the cup more appealing.
- Change the routine, not just the container. Replace the bedtime bottle with a story, a cuddle, and a cup of milk earlier in the evening, followed by tooth brushing.
- Brush after the last milk of the day. This is non-negotiable once teeth are present.
- Remove bottles from sight. Out of view genuinely reduces requests.
- Involve the child. Letting a toddler choose their cup increases acceptance considerably.
- Stay consistent. Giving in intermittently makes the process much longer.
Handling Common Difficulties
The Child Refuses the Cup
Try a different style, offer it when the child is thirsty rather than full, let them see older siblings or parents drinking from cups, and keep offering without pressure. Refusal usually resolves within one to two weeks.
Milk Intake Drops
Some reduction is expected and often appropriate, since many bottle-fed toddlers consume more milk than they need. Offer cheese, yoghurt, and other calcium sources. Discuss with a physician if intake remains very low.
Night Waking
If the bottle was a sleep association, expect a few unsettled nights. Offer water in a cup and comfort without the bottle. Most children adjust within three to seven nights.
Strong Emotional Attachment
Introduce a comfort object as a replacement, keep the bedtime routine otherwise identical, and consider a simple visual chart for older toddlers.
Bottle vs Cup: A Quick Comparison
- Sucking action: bottle requires sustained sucking. Cup requires sipping and lip closure.
- Contact time with teeth: bottle liquid pools around the front teeth. Cup liquid clears quickly.
- Duration of use: bottles encourage slow, extended feeding. Cups encourage finishing promptly.
- Oral development: cups support mature swallow patterns and speech readiness.
- Decay risk: significantly higher with prolonged bottle use, particularly at night.
- Independence: cups build self-feeding skills earlier.
Myths About Bottles and Children Dentistry
Myth: milk cannot cause cavities because it is natural. Milk contains lactose, a fermentable sugar. Pooled against teeth overnight it absolutely contributes to decay.
Myth: baby teeth do not need treatment. They hold space for adult teeth, support chewing and speech, and can cause serious infection if decay is left untreated.
Myth: dental treatment for toddlers is traumatic. Modern paediatric care emphasises familiarisation, gentle language, and short positive visits. Children who attend from the first birthday usually build no fear at all.
Myth: sippy cups are the same as regular cups. Valved sippy cups replicate bottle sucking. Free-flow or open cups are what dental professionals actually recommend.
Myth: you should wait until age three for the first dental visit. The recommendation is by the first birthday, or within six months of the first tooth erupting.
Safety Notes
- Never prop a bottle or leave a baby unattended while feeding, because of choking and aspiration risk.
- Do not add sugar, honey, cereal, or flavourings to a bottle. Honey is unsafe for infants under 12 months due to botulism risk.
- Supervise children with open cups to prevent choking on large gulps.
- Clean cups and valves thoroughly, as valved designs harbour mould.
- Start brushing as soon as the first tooth appears, twice daily with a smear of fluoride toothpaste.

Frequently Asked Questions
At what age should bottles be gone completely?
Most guidance recommends stopping between 12 and 18 months, with 12 months as the ideal target. Use beyond 18 months increases the risk of decay and bite changes and is worth discussing at a dental visit.
Is a sippy cup better than a bottle?
Only marginally, if it has a valve. Valved sippy cups require the same sucking action as a bottle and encourage all-day sipping. Free-flow beakers, straw cups, and open cups are the better options.
Can my child have milk in a cup at bedtime?
Yes, provided teeth are brushed afterwards. The problem is not milk itself but milk left on the teeth overnight. Serve it earlier in the routine, then brush, then only water afterwards.
What if my toddler refuses to drink anything from a cup?
Keep offering without pressure, try different cup styles, and offer when genuinely thirsty. Most children accept within one to two weeks. If intake is a genuine concern, speak to your physician or dentist rather than reverting long term.
Does bottle feeding cause crooked teeth?
Prolonged bottle and teat use can contribute to an open bite and a narrower upper arch, particularly beyond age two. Many of these changes improve on their own once the habit stops before the adult teeth erupt.
Conclusion
Introduce a cup around six months and aim to remove bottles completely between 12 and 18 months, saving the bedtime bottle for last. Never let a child sleep with anything but water, and brush after the final milk of the day. A dental checkup by the first birthday makes the whole transition easier and catches early problems while they are still reversible.
